+Subject: bpf: Add missing access_ok call to copy_user_syms
+
+From: Jiri Olsa <jolsa@kernel.org>
+
+commit d5dc200c3a3f217de072af269dd90adddf90e48d upstream.
+
+As reported by sashiko we use __get_user without prior access_ok call on the
+user space pointer. Adding the missing call for the whole pointer array.
+
+Plus removing the err check in the error path, because it's not needed and
+also we can return -ENOMEM directly from the first kvmalloc_array fail path.

+All the callers of mhi_ep_handle_syserr() except mhi_ep_process_cmd_ring()

+Subject: can: bcm: add missing rcu list annotations and operations
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit 7b2c3eabc4dafc062a25e10711154f2107526a78 upstream.
+
+sashiko-bot remarked the missing use of list_add_rcu() in
+bcm_[rx|tx]_setup() to have a proper initialized bcm_op structure
+when bcm_proc_show() traverses the bcm_op's under rcu_read_lock().
+
+To cover all initial settings of the bcm_op's the list_add_rcu() calls
+are moved to the end of the setup code.
+
+While at it, also fix the mirroring removal side: bcm_release() called
+bcm_remove_op() - which frees the op via call_rcu() - on ops that were
+still linked in bo->tx_ops/bo->rx_ops, without list_del_rcu() first.
+Unlink each op with list_del_rcu() before handing it to bcm_remove_op(),
+matching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op().

+Subject: can: bcm: defer rx_op deallocation to workqueue to fix thrtimer UAF
+
+From: Lee Jones <lee@kernel.org>
+
+commit 68973f9db76144825e4f35dfdc80fb8279eb2d57 upstream.
+
+Commit f1b4e32aca08 ("can: bcm: use call_rcu() instead of costly
+synchronize_rcu()") replaced synchronize_rcu() in bcm_delete_rx_op()
+with call_rcu() and introduced the RX_NO_AUTOTIMER flag.
+
+However, this flag check was omitted for thrtimer in the packet rx
+fast-path. During BCM RX operation teardown, a concurrent RCU reader
+(bcm_rx_handler) can race and re-arm thrtimer via
+bcm_rx_update_and_send() after call_rcu() has been scheduled. Once
+the RCU grace period elapses, bcm_op is freed. The subsequently
+firing thrtimer then dereferences the deallocated op, causing a UAF.
+
+Adding flag checks to the rx fast-path (bcm_rx_update_and_send) does not
+fully close the TOCTOU race and introduces latency for every CAN frame.
+Conversely, calling hrtimer_cancel() directly inside the RCU callback
+(softirq context) is fatal as hrtimer_cancel() can sleep, triggering
+a "scheduling while atomic" panic.
+
+Resolve this by deferring the timer cancellation and memory free to a
+dedicated unbound workqueue (bcm_wq). The RCU callback now queues a
+work item to bcm_wq, which safely cancels both timers and deallocates
+memory in sleepable process context. A dedicated workqueue is used to
+prevent system-wide WQ saturation and is cleanly flushed/destroyed
+on module unload to avoid rmmod page faults.
+
+Since the deferred work can now outlive the calling context by an
+unbounded amount, also take a reference on op->sk when it is assigned
+and drop it only once the deferred work has cancelled both timers, so a
+socket can no longer be freed out from under a still-armed timer whose
+callback (bcm_send_to_user()) dereferences op->sk.

+Subject: can: bcm: fix lockless bound/ifindex race and silent RX_SETUP failure
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit d9b091d9d22fee81ec53fb55d2032951993ceadb upstream.
+
+bcm_sendmsg() reads bo->ifindex and checks bo->bound before taking
+lock_sock(), while bcm_notify(), bcm_connect() and bcm_release() all
+mutate both fields under that same lock. Because the lockless reads
+and the locked writes are unordered with respect to each other, a
+racing bcm_notify() (device unregister) or bcm_connect() (concurrent
+bind on another thread sharing the socket) can make bcm_sendmsg()
+observe an inconsistent combination, e.g. a stale bound=1 together
+with the now-cleared ifindex=0, silently turning a socket bound to a
+specific CAN interface into one that also matches "any" interface.
+
+Keep the lockless bo->bound check purely as a fast-path reject, and
+move the ifindex read (and a bo->bound re-check) into the locked
+section, where every writer already serializes. This removes the
+possibility of observing the two fields torn against each other,
+rather than trying to fix it with more READ_ONCE()/WRITE_ONCE() pairs
+on two independently updated fields. Annotate the now-purely-lockless
+bo->bound accesses consistently across all its write sites.
+
+Also fix bcm_rx_setup() silently returning success when the target
+device disappears concurrently instead of reporting -ENODEV, so a
+broken RX op is no longer left registered as if it had succeeded.

+Subject: can: esd_usb: kill anchored URBs before freeing netdevs
+
+From: Fan Wu <fanwu01@zju.edu.cn>
+
+commit c43122fef328a70045fe7621c06de6b2b8e19264 upstream.
+
+esd_usb_disconnect() frees each CAN netdev with free_candev() inside
+its per-netdev loop and only calls unlink_all_urbs(dev) afterwards.
+The per-netdev private data (struct esd_usb_net_priv) is embedded in
+the net_device allocation returned by alloc_candev(), so once
+free_candev() has run, dev->nets[i] points to freed memory.
+unlink_all_urbs() then dereferences the freed dev->nets[i] to kill the
+per-netdev TX anchor (usb_kill_anchored_urbs(&priv->tx_submitted)),
+clear active_tx_jobs, and reset priv->tx_contexts[].
+
+Reorder the teardown so the anchored URBs are killed before the netdevs
+are freed, matching other CAN/USB drivers in the same directory such as
+ems_usb, usb_8dev and mcba_usb, which unregister, then unlink, then
+free: unregister the netdevs first (which stops their TX queues), call
+unlink_all_urbs(dev) once, then free the netdevs.
+
+This issue was found by an in-house static analysis tool.

+Subject: can: isotp: use unconditional synchronize_rcu() in isotp_release()
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit 9b1a02e0d980ac6b0e36a90378f847062f81d7e4 upstream.
+
+isotp_notify() unregisters the (RCU) CAN filters via can_rx_unregister()
+and clears so->bound without waiting for a grace period. isotp_release()
+uses so->bound to decide whether it needs to call synchronize_rcu()
+before cancelling so->rxtimer, so when NETDEV_UNREGISTER runs first it
+skips that synchronize_rcu() and can cancel the timer while an
+in-flight isotp_rcv() is still executing and about to re-arm it via
+isotp_send_fc(), leading to a use-after-free timer callback on the
+freed socket.
+
+sakisho-bot remarked a problem with rtnl_lock held in isotp_notify(),
+therefore make isotp_release() always call synchronize_rcu() before
+cancelling the timers, regardless of so->bound. This still closes the
+original race (isotp_notify() clearing so->bound without waiting for
+in-flight isotp_rcv() callers before isotp_release() cancels the RX
+timer) without adding any RCU wait to the netdevice notifier path.
+

+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit 422f1d4f141eaa3a6e4199ceec86cc6b9bf26570 upstream.
+
+block_to_sector converts a block number to a sector number and adds
+c->start to the result. It is inappropriate to use this function for
+converting the number of blocks to a number to sectors because c->start
+would be incorrectly added to the result.
+
+Luckily, the only target that uses dm_bufio_issue_discard is dm-ebs,
+which sets c->start to 0, so this bug is latent.

+Subject: dm era: fix out-of-bounds memory access for non-zero start sector
+
+From: Samuel Moelius <sam.moelius@trailofbits.com>
+
+commit a868196f03c2b19418ae3d2b69e195d668a271e5 upstream.
+
+dm-era tracks writes in target-relative blocks, but era_map() calculates
+the writeset block before applying the target offset. Tables with a
+non-zero start sector can therefore pass an absolute mapped-device block
+to metadata_current_marked().
+
+If the absolute block is beyond the current writeset size,
+writeset_marked() tests past the end of the in-core bitset. KASAN reports
+this as a vmalloc-out-of-bounds access.
+
+Apply the target offset before calculating the era block so writeset
+lookups use the target-relative block number.

+Subject: dm-log: fix a bitset_size overflow on 32bit machines
+
+From: Benjamin Marzinski <bmarzins@redhat.com>
+
+commit 9743132a41f4d9d0e54c5f2adcb821b04796bab1 upstream.
+
+Commit c20e36b7631d ("dm log: fix out-of-bounds write due to
+region_count overflow") made sure that region_count could fit in an
+unsigned int. But the bitmap memory isn't allocated based on
+region_count. It uses bitset_size (a size_t variable). The first step of
+calculating bitset_size is to set it to region_count, rounded up to a
+multiple of BITS_PER_LONG. If region_size is less than BITS_PER_LONG
+smaller than UINT_MAX, it will get rounded up to 2^32. On a 32bit
+architecture, this will make bitset_size wrap around to 0 and fail,
+despite region_count being valid.
+
+Since bitset_size gets divided by 8, it can hold any valid region_count.
+It just needs a special case to handle the rollover. If it is 0, the
+value rolled over, and bitset size should be set to the number of bytes
+needed to hold 2^32 bits.

+
+From: Ming-Hung Tsai <mtsai@redhat.com>
+
+commit 5bcd4d3058ebaf46ad2e163829d87dd4870c7a45 upstream.
+
+__reserve_metadata_snap() and __release_metadata_snap() modify the
+superblock's held_root directly in the block_manager's buffer. If the
+subsequent metadata commit fails, the held_root gets flushed to disk
+through the abort_transaction path, resulting in inconsistent metadata.
+
+Reproducer 1: __reserve_metadata_snap()
+
+1. Create a 2 MiB metadata device and make the region after the 14th
+ block inaccessible, to trigger metadata commit failure in the
+ subsequent reserve_metadata_snap operation. The 14th block will be
+ the shadow destination for the index block.
+

+
+2. Create a 16 MiB thin-pool
+

+dd if=/dev/zero of=/dev/mapper/tmeta bs=4k count=1
+dmsetup create tpool --table "0 32768 thin-pool /dev/mapper/tmeta \
+/dev/mapper/tdata 128 0 1 skip_block_zeroing"
+
+3. Take a metadata snapshot to trigger metadata commit failure and
+ transaction abort. However, the held_root is written to disk,
+ breaking metadata consistency.
+
+dmsetup message tpool 0 "reserve_metadata_snap"
+
+thin_check v1.2.2 result:
+
+Bad reference count for metadata block 6. Expected 2, but space map contains 1.
+Bad reference count for metadata block 7. Expected 2, but space map contains 1.
+Bad reference count for metadata block 13. Expected 1, but space map contains 0.
+
+Reproducer 2: __release_metadata_snap()
+
+1. Create a 2 MiB metadata device and make the region after the 16th
+ block inaccessible, to trigger metadata commit failure in the
+ subsequent release_metadata_snap operation. The 16th block will be
+ the shadow destination for the index block.
+
+dmsetup create tmeta --table "0 128 linear /dev/sdc 0

+dmsetup create tpool --table "0 32768 thin-pool /dev/mapper/tmeta \
+/dev/mapper/tdata 128 0 1 skip_block_zeroing"
+
+3. Reserve then release the metadata snapshot, to trigger metadata
+ commit failure and transaction abort. The held_root gets removed
+ from the on-disk superblock, causing inconsistent metadata.
+
+dmsetup message tpool 0 "reserve_metadata_snap"

+
+thin_check v1.2.2 result:
+
+Bad reference count for metadata block 6. Expected 1, but space map contains 2.
+Bad reference count for metadata block 7. Expected 1, but space map contains 2.
+1 metadata blocks have leaked.
+
+Fix by deferring the held_root update to commit time.
+
+Additionally, move the existing-snapshot check in __reserve_metadata_snap
+before the shadow operation to avoid unnecessary work. In
+__release_metadata_snap, clear pmd->held_root before btree deletion so
+partial failure leaks blocks rather than leaving a stale reference, and
+unlock the snapshot block before decrementing its refcount.

+From: Genjian Zhang <zhanggenjian@kylinos.cn>
+
+commit 4b22d0801fadfcae2e106e6ba32e49439c7c7ebf upstream.
+
+__reserve_metadata_snap() increments THIN_SUPERBLOCK_LOCATION in the
+metadata space map before shadowing it. When dm_tm_shadow_block()
+fails, a reference is leaked in the metadata space map.
+
+Fix by adding the missing dm_sm_dec_block().

+
+From: Frank Li <Frank.Li@nxp.com>
+
+commit 8ffba0171c6bbce5f093c6dba5a02c0805b31203 upstream.
+
+The DONE_INT_MASK and ABORT_INT_MASK registers are shared by all DMA
+channels, and modifying them requires a read-modify-write sequence.
+Because this operation is not atomic, concurrent calls to
+dw_edma_v0_core_start() can introduce race conditions if two channels
+update these registers simultaneously.
+
+Add a spinlock to serialize access to these registers and prevent race
+conditions.

+Subject: dmaengine: tegra: Fix burst size calculation
+
+From: Kartik Rajput <kkartik@nvidia.com>
+
+commit 4651df83b6c796daead3447e8fd874322918ee4f upstream.
+
+Currently, the Tegra GPC DMA hardware requires the transfer length to
+be a multiple of the max burst size configured for the channel. When a
+client requests a transfer where the length is not evenly divisible by
+the configured max burst size, the DMA hangs with partial burst at
+the end.
+
+Fix this by reducing the burst size to the largest power-of-2 value
+that evenly divides the transfer length. For example, a 40-byte
+transfer with a 16-byte max burst will now use an 8-byte burst
+(40 / 8 = 5 complete bursts) instead of causing a hang.
+
+This issue was observed with the PL011 UART driver where TX DMA
+transfers of arbitrary lengths were stuck.

+From: Sebastian Alba Vives <sebasjosue84@gmail.com>
+
+commit 43a1974da6bc7ce8f4d1dc1d03d56997428c29c3 upstream.
+
+mpf_ops_parse_header() reads header_size from the bitstream at
+MPF_HEADER_SIZE_OFFSET (24). When header_size is zero, the expression
+*(buf + header_size - 1) reads one byte before the buffer start.
+
+Since initial_header_size is set to 71 in mpf_ops, the fpga-mgr core
+guarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET.
+The only real gap is the zero header_size case, which cannot be
+resolved by providing a larger buffer, so return -EINVAL.

+Subject: irqchip/crossbar: Use correct index in crossbar_domain_free()
+
+From: Bhargav Joshi <j.bhargav.u@gmail.com>
+
+commit 043db005a8d6932dc7d217c86307e9af0bc10ddc upstream.
+
+crossbar_domain_free() resets the domain data and then uses the nulled
+out irq_data->hwirq member as index to reset the irq_map[] entry and to
+write the relevant crossbar register with a safe entry. That means it
+never frees the correct index and keeps the crossbar register connection
+to the source interrupt active.
+
+If it would not reset the domain data, then this would be even worse as
+irq_data->hwirq holds the source interrupt number, but both the map and
+register index need the corresponding GIC SPI number and not the source
+interrupt number. This might even result in an out of bounds access as
+the source interrupt number can be higher than the maximal index space.
+
+Fix this by using the GIC SPI index from the parent domain's irq_data.

+Subject: ksmbd: fix integer overflow in set_file_allocation_info()
+
+From: Ibrahim Hashimov <security@auditcode.ai>
+
+commit 1c0ae3df692ea2a4ce992f786346154e75a3f0d5 upstream.
+
+set_file_allocation_info() converts the client-supplied
+FILE_ALLOCATION_INFORMATION::AllocationSize into a 512-byte block
+count with:
+
+ alloc_blks = (le64_to_cpu(file_alloc_info->AllocationSize) + 511) >> 9;
+
+AllocationSize is a fully client-controlled __le64 field; the only
+validation performed by the caller (smb2_set_info_file(), case
+FILE_ALLOCATION_INFORMATION) is that the fixed buffer is at least
+sizeof(struct smb2_file_alloc_info) == 8 bytes. The value itself is
+never range-checked before this arithmetic.
+
+When AllocationSize is close to U64_MAX (e.g. 0xffffffffffffffff),
+"AllocationSize + 511" wraps around mod 2^64 to a small number
+(0xffffffffffffffff + 511 = 510), so alloc_blks becomes 0. Since any
+existing regular file has stat.blocks > 0, the function then takes
+the "shrink" branch and calls:
+
+ ksmbd_vfs_truncate(work, fp, alloc_blks * 512); /* == 0 */
+
+silently truncating the file to size 0, even though the client asked
+to grow the allocation to (what looks like) the maximum possible
+size. The trailing "if (size < alloc_blks * 512) i_size_write(inode,
+size);" restore is guarded by a comparison that is never true once
+alloc_blks == 0, so the truncation is not undone. This lets an
+authenticated SMB client that already holds an open handle with
+FILE_WRITE_DATA on a file silently truncate that same file to size 0
+via a single crafted SET_INFO(FILE_ALLOCATION_INFORMATION) request
+advertising a near-U64_MAX AllocationSize, even though the request
+asks to grow the file's allocation rather than shrink it. This is a
+functional/data-loss bug, not a privilege-boundary
+violation: the same client could already truncate the file via
+FILE_END_OF_FILE_INFORMATION or a plain write.
+
+Fix it by validating AllocationSize against MAX_LFS_FILESIZE, the
+same upper bound the VFS itself uses to reject unrepresentable file
+sizes, before doing the "+511" rounding, and rejecting oversized
+values with -EINVAL. Bounding AllocationSize to
+MAX_LFS_FILESIZE - 511 guarantees the "+511" addition cannot wrap,
+and that the subsequent "alloc_blks * 512" values passed to
+vfs_fallocate() and ksmbd_vfs_truncate() stay within a representable
+loff_t as well.
+
+No legitimate SMB client asks for an allocation size anywhere near
+2^64 bytes, so this only rejects a value that was previously
+silently misinterpreted as zero.
+
+Runtime-verified on a v6.19 KASAN test stand: sending SET_INFO
+(FILE_ALLOCATION_INFORMATION) with AllocationSize = 0xffffffffffffffff
+against ksmbd now returns -EINVAL and leaves the target file's size
+unchanged, where the unpatched kernel truncated it from 4096 to 0
+bytes.

+Subject: mtd: spi-nor: swp: Improve locking user experience
+
+From: Miquel Raynal <miquel.raynal@bootlin.com>
+
+commit e1d456b26bf23e30db305a6184e8abd9ab68bbf2 upstream.
+
+In the case of the first block being locked (or the few first blocks),
+if the user want to fully unlock the device it has two possibilities:
+- either it asks to unlock the entire device, and this works;
+- or it asks to unlock just the block(s) that are currently locked,
+ which fails.
+
+It fails because the conditions "can_be_top" and "can_be_bottom" are
+true. Indeed, in this case, we unlock everything, so the TB bit does not
+matter. However in the current implementation, use_top would be true (as
+this is the favourite option) and lock_len, which in practice should be
+reduced down to 0, is set to "nor->params->size - (ofs + len)" which is
+a positive number. This is wrong.
+
+An easy way is to simply add an extra condition. In the unlock() path,
+if we can achieve the same result from both sides, it means we unlock
+everything and lock_len must simply be 0. A comment is added to clarify
+that logic.

+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit 48c0162f647bb47e6084ffbc71b8f213f5e2f4f8 upstream.
+
+nvmet_rdma_use_inline_sg() maps the host-controlled inline data offset
+into the per-command inline scatterlist. The bounds check admits any
+offset with off + len <= inline_data_size, but the mapping still assumes
+the data begins in the first inline page:
+
+ sg->offset = off;
+ sg->length = min_t(int, len, PAGE_SIZE - off);
+
+When a port is configured with inline_data_size > PAGE_SIZE (settable up
+to max(SZ_16K, PAGE_SIZE)), an offset in (PAGE_SIZE, inline_data_size]
+makes "PAGE_SIZE - off" underflow, so sg->length is set to ~4 GiB and
+the block backend reads far past the first inline page. num_pages(len)
+also ignores the offset, so an in-bounds offset whose [off, off+len)
+span crosses a page boundary under-counts the scatterlist.
+
+Map the offset properly: split it into a page index and an in-page
+offset, start the scatterlist at that page, and size the page count from
+page_off + len. Because the request scatterlist may now start at
+inline_sg[page_idx] rather than inline_sg[0], generalize the inline-SGL
+identity test in nvmet_rdma_release_rsp() to a range test; otherwise the
+persistent inline scatterlist is mistaken for an allocated one and
+nvmet_req_free_sgls() frees an inline page (and warns in
+free_large_kmalloc()).

+From: WenTao Liang <vulab@iscas.ac.cn>
+
+commit 2c007acf7b31c39c08ce4959451ad00b19be4c1f upstream.
+
+When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path
+returns -ENOSPC without releasing the reference obtained via
+kref_get_unless_zero() earlier in the function. All other error paths
+correctly drop the reference. This causes a permanent reference leak on the
+io_to_abort object.
+
+Additionally, the abort_in_progress flag is left set to true on this path,
+which means future abort attempts for the same I/O will immediately return
+-EINPROGRESS even though the abort was never submitted, effectively
+blocking recovery.
+
+Fix this by adding the missing kref_put() call and reset abort_in_progress
+to false, matching the cleanup done in the efct_hw_wq_write() failure path
+below.

+commit e166bafc483e927150cb9b5f286c9191ea0df84e upstream.
+
+If phys_disk->in_reset is set, the function returns directly without
+undoing the resources acquired for the command. Add the missing error
+cleanup by unmapping the IOACCEL2 SG chain block when needed, unmapping
+the SCSI command, and dropping the outstanding IOACCEL command count
+before returning.

+commit 1bd28625e25be549ee7c47532e7c3ef91c682410 upstream.
+
+The memory allocated for mboxq using mempool_alloc() is not freed in

+
+From: Xu Rao <raoxu@uniontech.com>
+
+commit 1d3a742afeb761eaead774691bde1ced699e9a5d upstream.
+
+SG_GET_REQUEST_TABLE reports per-request diagnostic state through
+sg_req_info::problem. The field is meant to indicate whether there is an
+error to report for a completed request.
+
+sg_fill_request_table() currently combines masked_status, host_status
+and driver_status with bitwise AND. This only reports a problem when all
+three status fields are non-zero at the same time. A normal target check
+condition, for example, has masked_status set while host_status and
+driver_status may both be zero, so the request is incorrectly reported
+as clean.
+
+Use the same condition as sg_new_read(), which sets SG_INFO_CHECK when
+any of the three status fields is non-zero.

+Subject: scsi: target: Bound PR-OUT TransportID parsing to the received buffer
+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit d04a179085c262c9ed577d0a4cbc6482ff1fd9a3 upstream.
+
+core_scsi3_decode_spec_i_port() and core_scsi3_emulate_register_and_move()
+hand the raw PERSISTENT RESERVE OUT parameter buffer to
+target_parse_pr_out_transport_id() without telling it how many bytes are
+valid. For an iSCSI TransportID (FORMAT CODE 01b),
+iscsi_parse_pr_out_transport_id() locates the ",i,0x" ISID separator with
+an unbounded strstr() (and on the error path prints the name with a further
+unbounded "%s"). An initiator can submit a TransportID whose iSCSI name
+contains neither a ",i,0x" substring nor a NUL terminator, filling the
+parameter list to its end, so the scan runs off the end of the buffer.
+
+When the parameter list spans more than one page the buffer is a multi-page
+vmap (transport_kmap_data_sg()), so the over-read walks into the trailing
+vmalloc guard page and oopses (KASAN: vmalloc-out-of-bounds in strstr). It
+is reachable by any fabric that delivers a PR OUT to a device exported
+through an iSCSI TPG, including a guest via vhost-scsi.
+
+Pass the number of received bytes down to the parser and validate the iSCSI
+TransportID's own self-described length (ADDITIONAL LENGTH + 4) once, up
+front: reject it if it is below the spc4r17 minimum or larger than the
+received buffer, then bound the separator search, the ISID walk and the
+name copy by that length. This is the length check the callers already
+perform after the parse (core_scsi3_decode_spec_i_port() compares tid_len
+against tpdl, core_scsi3_emulate_register_and_move() validates it against
+data_length), moved ahead of the scan. Also drop the unbounded "%s" of the
+unterminated name.
+
+Add per-format explicit name-length checks before copying into i_str,
+rather than silently truncating with min_t: for FORMAT CODE 00b reject if
+the descriptor body (tid_len - 4 bytes) cannot fit in
+i_str[TRANSPORT_IQN_LEN]; for FORMAT CODE 01b reject if the name portion
+(from &buf[4] up to the separator) cannot fit. Both checks make the bounds
+intent explicit at each format branch.
+
+While here, also reject a FORMAT CODE 01b TransportID whose ",i,0x"
+separator sits at the very end of the descriptor: that leaves an empty ISID
+and points the returned port nexus pointer at buf + tid_len, one past the
+descriptor, which the registration code (__core_scsi3_locate_pr_reg(),
+__core_scsi3_alloc_registration()) then dereferences as the ISID string --
+the same over-read of the parameter buffer for a malformed descriptor.

+Subject: scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE
+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit fda6a1f3c3d7047b5ce5654487649c2daa738bfc upstream.
+
+core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT
+parameter list with transport_kmap_data_sg() and parses the destination
+TransportID with target_parse_pr_out_transport_id(). For an iSCSI
+TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns
+the ISID in iport_ptr as a raw pointer into that mapped buffer.
+
+The function then unmaps the buffer with transport_kunmap_data_sg() before
+dereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and
+core_scsi3_alloc_registration(). When the parameter list spans more than
+one page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses
+vmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual
+address backing iport_ptr is torn down and every subsequent dereference is
+a use-after-free read of the unmapped region.
+
+Keep the parameter list mapped until iport_ptr is no longer needed: drop
+the early transport_kunmap_data_sg() and unmap once on the success path,
+right before returning. The error paths already unmap through the existing
+"if (buf) transport_kunmap_data_sg(cmd)" at the out: label, which now runs
+on every post-map error exit because buf is no longer cleared early. Only
+reads of the mapping happen while spinlocks are held; the map and unmap
+calls remain outside any lock. The sibling caller
+core_scsi3_decode_spec_i_port() already uses the buffer before unmapping it
+and is left unchanged.

+Subject: scsi: xen: scsiback: Free the command tag on the TMR submit-failure path
+
+From: Michael Bommarito <michael.bommarito@gmail.com>
+
+commit 66aefc277ebb796ec285d550305535dc3fc0179f upstream.
+
+scsiback_device_action() obtains a command tag in
+scsiback_get_pend_req() and submits a task-management request with
+target_submit_tmr(). When target_submit_tmr() fails it returns < 0 and
+scsiback jumps to the err: label, which sends a response but frees
+nothing, leaking the tag.
+
+Impact: a pvSCSI guest can leak the command tags of a LUN's session,
+stopping the LUN, by issuing VSCSIIF_ACT_SCSI_ABORT or RESET requests
+whenever target_submit_tmr() fails.
+
+transport_generic_free_cmd() cannot be used here. By the time
+target_submit_tmr() returns an error it has already run
+__target_init_cmd() (so se_cmd->cmd_kref is one, not zero), and on its
+target_get_sess_cmd() error path it has freed se_cmd->se_tmr_req via
+core_tmr_release_req() while leaving SCF_SCSI_TMR_CDB set and the
+pointer dangling. Letting the command release run target_free_cmd_mem()
+would then double-free se_tmr_req.
+
+Use the same helper, which returns just the tag, on this path too.

+Subject: scsi: xen: scsiback: Free unsubmitted command instead of double-putting it
+
+From: Michael Bommarito <michael.bommarito@gmail.com>
+
+commit ca978f8a93d4d36841839bf2847d29b88c2591d6 upstream.
+
+scsiback_get_pend_req() obtains a command tag and returns a vscsibk_pend
+whose embedded se_cmd has only been memset to 0, so its cmd_kref is 0;
+the se_cmd is initialised (kref_init() via target_init_cmd()) only
+later, in scsiback_cmd_exec(), on the successful VSCSIIF_ACT_SCSI_CDB
+path. The two error paths in scsiback_do_cmd_fn() taken before the
+command is submitted -- a failed scsiback_gnttab_data_map() and an
+unknown ring_req.act -- call
+transport_generic_free_cmd(&pending_req->se_cmd, 0), which kref_put()s a
+refcount of 0. That underflows it ("refcount_t: underflow;
+use-after-free") and, as the release function is not run, leaks the
+command tag.
+
+Impact: a pvSCSI guest can leak every command tag of a LUN's session,
+stopping the LUN, by submitting requests with a bad grant reference or
+an unknown request type; under panic_on_warn the refcount underflow
+panics the host.
+
+Add a helper that just returns the tag with target_free_tag() and sends
+the error response. It frees the tag while the v2p reference still pins
+the session, and snapshots the response fields beforehand because
+freeing the tag can let another ring reuse the pending_req slot.
+

+Subject: sctp: validate STALE_COOKIE cause length before reading staleness
+
+From: Weiming Shi <bestswngs@gmail.com>
+
+commit 1cd23ca80784223fa2204e16203f754da4e821f8 upstream.
+
+When an ERROR chunk with a STALE_COOKIE cause is received in the
+COOKIE_ECHOED state, sctp_sf_do_5_2_6_stale() reads the 4-byte Measure
+of Staleness that follows the cause header:
+
+ err = (struct sctp_errhdr *)(chunk->skb->data);
+ stale = ntohl(*(__be32 *)((u8 *)err + sizeof(*err)));
+
+err is the first cause in the chunk, not the STALE_COOKIE cause that
+caused the dispatch, and nothing guarantees the staleness field is
+present. sctp_walk_errors() only requires a cause to be as long as the
+4-byte header, so for a STALE_COOKIE cause of length 4 the read runs
+past the cause, and for a minimal ERROR chunk past skb->tail. The value
+is echoed to the peer in the Cookie Preservative of the reply INIT,
+leaking uninitialized memory.
+
+sctp_sf_cookie_echoed_err() already walks to the STALE_COOKIE cause, so
+check its length there and pass it to sctp_sf_do_5_2_6_stale(), which
+reads that cause instead of the first one. A STALE_COOKIE cause too
+short to hold the staleness field is discarded.
+
+The read is reachable by any peer that can drive an association into
+COOKIE_ECHOED, including an unprivileged process using a raw SCTP socket
+in a user and network namespace.

+Subject: smb: client: use kvzalloc() for megabyte buffer in simple fallocate
+
+From: Fredric Cover <fredric.cover.lkernel@gmail.com>
+
+commit 806c00c23e3ce8eae397a40ced536ef88ae4e012 upstream.
+
+Currently in smb3_simple_fallocate_range(), a 1 MB buffer is allocated
+using kzalloc(). Under heavy memory fragmentation, a contiguous 1 MB block
+of physical memory (an order-8 allocation) may not be available,
+causing the allocation to fail.
+
+This failure was observed during xfstests generic/013 on a 4GB RAM
+test machine running fsstress:
+
+fsstress: page allocation failure: order:8,
+mode:0x40dc0(GFP_KERNEL|__GFP_ZERO|__GFP_COMP),
+nodemask=(null),cpuset=/,mems_allowed=0

+
+Since this scratch buffer does not require physically contiguous memory,
+switch the allocation to kvzalloc(). This retains the performance
+benefits of kmalloc() under normal conditions, while gracefully falling
+back to virtually contiguous memory when physical allocation fails.

+Subject: spi: uniphier: Fix completion initialization order before devm_request_irq()
+
+From: Kunihiko Hayashi <hayashi.kunihiko@socionext.com>
+
+commit f3ad1c87d8201e54b66bd6072442f0b5d5a308ee upstream.
+
+The driver calls devm_request_irq() before initializing the completion
+used by the interrupt handler. Because the interrupt may occur immediately
+after devm_request_irq(), the handler may execute before init_completion().
+
+This may result in calling complete() on an uninitialized completion,
+causing undefined behavior. This has been observed with KASAN.
+
+Fix this by initializing the completion before registering the IRQ.

+Subject: time: Fix off-by-one in compat settimeofday() usec validation
+
+From: Wang Yan <wangyan01@kylinos.cn>
+
+commit 269f2b43fae692d1f3988c9f888a6301aa537b82 upstream.
+
+The compat version of settimeofday() uses '>' instead of '>=' when
+validating tv_usec against USEC_PER_SEC, allowing the value 1000000 to pass
+the check. After the subsequent conversion to nanoseconds (tv_nsec *=
+NSEC_PER_USEC), this results in tv_nsec == NSEC_PER_SEC, which violates the
+timespec invariant that tv_nsec must be strictly less than NSEC_PER_SEC.
+
+The native settimeofday() was already fixed in commit ce4abda5e126 ("time:
+Fix off-by-one in settimeofday() usec validation"), but the compat
+counterpart was missed.
+
+Fix it by using '>=' to reject tv_usec values outside the valid range [0,
+USEC_PER_SEC - 1].

+
+From: Thorsten Blum <thorsten.blum@linux.dev>
+
+commit 1a58f6115bfb34eabcc7de8a3a9745b219179781 upstream.
+
+Commit 186d124f07da ("tpm_eventlog.c: fix binary_bios_measurements")
+split the output to write the endian-converted event header first and
+then the variable-length event data.
+
+However, the split was at sizeof(struct tcpa_event) - 1, even though
+event_data was a zero-length array, and later a flexible array member,
+both of which already excluded the event data.
+
+Therefore, the current code writes the first three bytes of event_size
+from the endian-converted header and then the last byte from the raw
+header, which can emit a corrupted event_size on PPC64, where
+do_endian_conversion() maps to be32_to_cpu().
+
+Split one byte later to write the full endian-converted header first,
+followed by the variable-length event->event_data.

+Subject: tpm: Make the TPM character devices non-seekable
+
+From: Jaewon Yang <yong010301@gmail.com>
+
+commit f20d61c22bcaf172d6790b6500e3838e532e71c8 upstream.
+
+The TPM character devices expose a sequential command/response
+interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
+enabled.
+
+After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
+passes 0x1400 as *off to tpm_common_read(). The transfer length is
+bounded by response_length, but the offset is used unchecked when
+forming data_buffer + *off. A sufficiently large offset therefore causes
+an out-of-bounds heap read through copy_to_user() and, if the copy
+succeeds, an out-of-bounds zero-write through the following memset().
+
+Positional I/O does not provide coherent semantics for this interface.
+An arbitrary pread offset cannot represent how much of a response has
+been consumed sequentially. The write callback always stores a command
+at the start of data_buffer, while pwrite() does not update file->f_pos
+and can leave the sequential read cursor stale.
+
+Call nonseekable_open() from both open handlers. This removes
+FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
+fail with -ESPIPE before reaching the TPM callbacks, and explicitly
+marks the files non-seekable. Normal read() and write() continue to use
+the existing sequential f_pos cursor, leaving the response state machine
+unchanged.
+
+Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
+
+ - sequential partial reads returned the complete response
+ - pread() and preadv() with offset 0x1400 returned -ESPIPE
+ - pwrite() and pwritev() with offset zero returned -ESPIPE
+ - the pending response remained intact after the rejected operations
+ - a subsequent normal command/response cycle completed normally
+ - no KASAN report was produced.
+
+Fixes: 9488585b21be ("tpm: add support for partial reads")

+Subject: tpm: tpm_tis_spi: Use wait_woken() in wait_for_tmp_stat()
+
+From: Jarkko Sakkinen <jarkko@kernel.org>
+
+commit c0c9cfb3b75def8bf200a2d4db09015806acfeaf upstream.
+
+wait_event_interruptible_timeout() evaluates its condition after setting
+the current task state to TASK_INTERRUPTIBLE.
+
+With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
+path is used:
+
+ tpm_tis_status()
+ tpm_tis_spi_read_bytes()
+ tpm_tis_spi_transfer_full()
+ spi_bus_lock()
+ mutex_lock()
+
+Address this with the following measures:
+
+1. Call wait_tpm_stat_cond() only while tasking is running.
+2. Use wait_woken() to wait for changes.

+Subject: xen/gntdev: fix error handling in ioctl
+
+From: Wentao Liang <vulab@iscas.ac.cn>
+
+commit 45ca1afe2fd14c04e37227e79d3f8455831d8408 upstream.
+
+When gntdev_ioctl_map_grant_ref() fails to copy the operation result
+back to userspace after successfully adding the mapping to the list,
+the error path returns -EFAULT without releasing the reference
+acquired by gntdev_alloc_map(). The mapping remains in priv->maps
+with a refcount of 1, causing a memory leak and a dangling list
+entry.
+
+Additionally, gntdev_add_map() may modify map->index to avoid overlap
+with existing mappings. Therefore, the index returned to userspace
+must be obtained after gntdev_add_map() completes.
+
+Fix this by holding the mutex across gntdev_add_map(), retrieving
+the correct index, and copy_to_user(). If copy_to_user() fails,
+remove the mapping from the list and release the reference while
+still holding the lock.
+
+Cc: stable@vger.kernel.org
+
+Fix these issues by properly handling all error cases.

+Subject: xfrm: use compat translator only for u64 alignment mismatch
+
+From: Sanman Pradhan <psanman@juniper.net>
+
+commit 355fbcbdc2539cca7890b0d0914d4ce0f985ad74 upstream.
+
+The XFRM compat layer (CONFIG_XFRM_USER_COMPAT) translates 32-bit xfrm
+netlink and setsockopt messages into the native 64-bit layout. It is
+only needed on architectures where the 32-bit and 64-bit ABIs disagree
+on u64 alignment, which the kernel encodes as COMPAT_FOR_U64_ALIGNMENT.
+
+That symbol is defined only by arch/x86. XFRM_USER_COMPAT depends on it,
+so the translator can never be built on any other architecture,
+including arm64, which still provides a 32-bit compat ABI (CONFIG_COMPAT)
+for AArch32 EL0 userspace. On arm64 the AArch32 EABI already aligns u64
+to 8 bytes, identical to the AArch64 ABI, so no translation is required
+and the native code path is correct for 32-bit tasks.
+
+However, xfrm_user_rcv_msg() and xfrm_user_policy() gate on
+in_compat_syscall() alone and then call xfrm_get_translator(), which
+returns NULL when no translator is registered. On arm64 that is always
+the case, so every xfrm netlink message and the XFRM_POLICY setsockopt
+issued by a 32-bit task returns -EOPNOTSUPP. A 32-bit userspace process
+on arm64 (and on any other arch with CONFIG_COMPAT but without
+COMPAT_FOR_U64_ALIGNMENT) therefore cannot configure XFRM state or
+policy through the XFRM_USER netlink API, and cannot use the XFRM_POLICY
+setsockopt path, because both fail before reaching the native parser.
+
+The translator series replaced the blanket compat rejection with a
+translator lookup. That made the path usable on x86 when the translator
+is available, but left architectures that cannot build the translator
+permanently rejected even when their compat layout already matches the
+native layout. Let those architectures use the native parser instead.
+
+Gate the translator requirement on COMPAT_FOR_U64_ALIGNMENT instead of
+on in_compat_syscall() alone. Gating on the ABI property rather than on
+CONFIG_XFRM_USER_COMPAT is deliberate: on x86 with IA32_EMULATION=y but
+XFRM_USER_COMPAT=n, a 32-bit task must still be rejected rather than
+routed through the native parser, which would misread genuinely
+4-byte-aligned x86-32 messages. COMPAT_FOR_U64_ALIGNMENT is the ABI
+property that makes the XFRM translator mandatory.
+
+Only the receive/input direction needs the guard. The send, dump and
+notification paths already call the translator as "if (xtr) { ... }"
+with no error on NULL, so on arches without a translator they no-op and
+the kernel emits native 64-bit-layout messages, which is what an AArch32
+task expects.
+
+Tested on Juniper SRX hardware: with the fix, 32-bit IPsec userspace
+netlink and XFRM_POLICY setsockopt operations that previously failed
+with -EOPNOTSUPP now succeed; x86 behaviour is unchanged by inspection.

+Subject: xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink
+
+From: Maoyi Xie <maoyixie.tju@gmail.com>
+
+commit 095515d89b19b6cc19dfcdc846f97403ed1ebce3 upstream.
+
+xfrmi_changelink() operates on at most two netns, dev_net(dev) and the
+interface link netns xi->net. They differ once the device is created in
+or moved to a netns other than the one the request runs in. The rtnl
+changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
+caller privileged there but not in xi->net can rewrite an interface that
+lives in xi->net.
+
+Gate xfrmi_changelink() on rtnl_dev_link_net_capable() at its top,
+before any attribute is parsed.
