+Subject: Bluetooth: btrtl: validate firmware patch bounds
+
+From: Laxman Acharya Padhya <acharyalaxman8848@gmail.com>
+
+commit 609c5b04a28dc1b0f3af6a7bc93055135b2d2059 upstream.
+
+rtlbt_parse_firmware() copies patch_length - 4 bytes before appending the
+firmware version. A malformed firmware patch shorter than the version field
+can make this subtraction underflow and turn the copy into an oversized
+read and write during Bluetooth setup.
+
+The existing patch_offset + patch_length check can also wrap on 32-bit
+architectures. Validate the patch length and range without arithmetic
+overflow before allocating or copying the patch.

+Subject: ipvs: fix more places with wrong ipv6 transport offsets
+
+From: Julian Anastasov <ja@ssi.bg>
+
+commit b3fe4cbd583895987935a9bdad01c8f9d3a02310 upstream.
+
+Sashiko reports for more incorrect IPv6 transport offsets.
+
+The app code for TCP was assuming IPv4 network header
+even after the ipvsh argument was provided. This can
+cause problems with apps over IPv6. As for the only
+official app in the kernel tree (FTP) this problem is
+harmless because we use Netfilter to mangle the FTP
+ports and we do not adjust the TCP seq numbers.
+
+Also, provide correct offset of the ICMPV6 header in
+ip_vs_out_icmp_v6() for correct checksum checks when
+the IPv6 packet has extension headers.
+
+Fixes: d12e12299a69 ("ipvs: add ipv6 support to ftp")
+Fixes: 2a3b791e6e11 ("IPVS: Add/adjust Netfilter hook functions and helpers for v6")

+
+From: Xuanqiang Luo <luoxuanqiang@kylinos.cn>
+
+commit 2c72eb6286347d05a885412fb076993bd5286b53 upstream.
+
+llc_sap_add_socket() takes a SAP reference for each socket added to a SAP,
+and llc_sap_remove_socket() releases it. llc_create_incoming_sock() takes
+an additional SAP reference after adding the child socket.
+
+This extra reference was balanced by an explicit llc_sap_put() in
+llc_ui_release() until commit 3100aa9d74db ("llc: fix SAP reference
+counting w.r.t. socket handling") removed that put. The corresponding hold
+in the accept path was left behind.
+
+When such a child socket is removed, only the reference taken by
+llc_sap_add_socket() is released. The extra reference keeps the SAP alive
+after its last socket is removed. Remove the obsolete hold.
+
+Fixes: 3100aa9d74db ("llc: fix SAP reference counting w.r.t. socket handling")

+Subject: macsec: fix promiscuity refcount leak in macsec_dev_open()
+
+From: James Raphael Tiovalen <jamestiotio@gmail.com>
+
+commit 7410d11460eb90d6c9281162ccc6a128534d897d upstream.
+
+When a MACsec interface with IFF_PROMISC set is brought up on top of a
+device that has hardware offload enabled, macsec_dev_open() first calls
+dev_set_promiscuity(real_dev, 1) and then propagates the open to the
+offload device. If that propagation fails, the error path jumps to the
+clear_allmulti label, which only reverts allmulti and the unicast
+address. The promiscuity taken on the lower device is never dropped, so
+real_dev is left permanently stuck in promiscuous mode. Its promiscuity
+count can no longer be balanced from software.
+
+Add a clear_promisc label that drops the promiscuity reference and
+route the two offload failure paths to it. The dev_set_promiscuity()
+failure itself still jumps to clear_allmulti, since on that failure the
+count was not incremented.

+Subject: memstick: ms_block: reject a card that reports too many blocks
+
+From: Maoyi Xie <maoyixie.tju@gmail.com>
+
+commit 718178f524b98bc920d74bc771aed823c8b81425 upstream.
+
+msb_ftl_initialize() computes the zone count from the card block count
+with no bound:
+
+ msb->zone_count = msb->block_count / MS_BLOCKS_IN_ZONE;
+ ...
+ for (i = 0; i < msb->zone_count; i++)
+ msb->free_block_count[i] = MS_BLOCKS_IN_ZONE;
+
+msb->block_count is a card value. msb_read_boot_blocks() reads
+number_of_blocks from the card boot page and byte swaps it.
+free_block_count is a fixed int[MS_MAX_ZONES]. MS_MAX_ZONES is 16, so the
+valid indices are 0 to 15. The init loop above indexes it by zone_count.
+msb_mark_block_used() and msb_mark_block_unused() index it by
+pba / MS_BLOCKS_IN_ZONE, for pba up to block_count - 1. A card may report
+up to 65535 blocks. A block_count above 8192 (MS_MAX_ZONES *
+MS_BLOCKS_IN_ZONE) lets the pba index reach 16. That writes past
+free_block_count[] and corrupts struct msb_data. A larger count runs the
+init loop past the end too.
+
+A real Memory Stick has at most 16 zones. So it has at most 8192 blocks.
+msb_ftl_initialize() now rejects a card that reports more than
+MS_MAX_ZONES * MS_BLOCKS_IN_ZONE blocks.

+Subject: net: openvswitch: reject oversized nested action attrs
+
+From: Asim Viladi Oglu Manizada <manizada@pm.me>
+
+commit 3f1f755366687d051174739fb99f7d560202f60b upstream.
+
+Open vSwitch stores generated flow actions as nlattrs, whose nla_len
+field is u16. Commit a1e64addf3ff ("net: openvswitch: remove
+misbehaving actions length check") allowed the total sw_flow_actions
+stream to grow beyond 64 KiB, which is valid, but also removed the last
+guard preventing a generated nested action attribute from exceeding
+U16_MAX.
+
+An oversized generated container can thus be closed with a truncated
+nla_len. A later dump or teardown then walks a structurally different
+stream than the one that was validated. In particular, an oversized
+nested CLONE/CT action may cause subsequent bytes in the generated
+stream to be interpreted as independent actions.
+
+Keep the larger total-action-stream behavior, but make nested action
+close reject generated containers that do not fit in nla_len, and return
+the error through all callers. For recursive SAMPLE, CLONE, DEC_TTL, and
+CHECK_PKT_LEN builders, trim resource-owning action-list tails in reverse
+construction order before discarding failed wrappers, so resources copied
+into the rejected tails are released before the wrappers are removed.
+
+Most failed outer wrappers are discarded by truncating actions_len after
+child resources have been released. CHECK_PKT_LEN also trims its parent
+after branch resources are gone. SET/TUNNEL close failures unwind their
+known tun_dst ownership directly, and SET_TO_MASKED has no external
+ownership and truncates on close failure.
+
+Fixes: a1e64addf3ff ("net: openvswitch: remove misbehaving actions length check")

+Subject: regulator: ltc3676: Fix incorrect IRQSTAT bit offsets
+
+From: Abhishek Ojha <Abhishek.ojha@savoirfairelinux.com>
+
+commit 50dce2e2f84b56d8b4b406d97a1543709e8a87f5 upstream.
+
+The LTC3676_IRQSTAT_* bit definitions do not match the IRQSTAT
+(Interrupt Request Status) register layout documented in Table 15
+of the LTC3676/LTC3676-1 datasheet:
+
+ bit 0 - Pushbutton Status Active
+ bit 1 - Hard Reset Occurred
+ bit 2 - PGOOD Timeout Occurred
+ bit 3 - Undervoltage Warning
+ bit 4 - Undervoltage Standby (Fault) Occurred
+ bit 5 - Overtemperature Warning
+ bit 6 - Overtemperature Standby (Fault) Occurred
+ bit 7 - Reserved
+
+The driver instead defines these starting at bit 3, one bit higher
+than the datasheet specifies, which causes ltc3676_regulator_isr()
+to check the wrong status bits and misreport (or miss) PGOOD
+timeout, undervoltage and thermal warning/fault conditions.
+
+Fix the bit offsets to match the datasheet.

+Subject: reset: imx7: Correct polarity of MIPI CSI resets on i.MX8MQ
+
+From: Robby Cai <robby.cai@nxp.com>
+
+commit 71827776667f4e4677a4fa806bcfb24d4b8dd9d7 upstream.
+
+On i.MX8MQ, the MIPI CSI reset lines are active-low and not self-clearing.
+Writing '0' asserts reset and it remains asserted until explicitly
+deasserted by software.
+
+This driver previously treated the MIPI CSI reset signals as active-high,
+which led to incorrect reset assert/deassert sequencing. This issue was
+exposed by commit 6d79bb8fd2aa ("media: imx8mq-mipi-csi2: Explicitly
+release reset").
+
+Fix this by reflecting the correct reset polarity and ensuring proper
+reset handling.
+
+Fixes: c979dbf59987 ("reset: imx7: Add support for i.MX8MQ IP block variant")

+
+From: Dawei Feng <dawei.feng@seu.edu.cn>
+
+commit 95fc02722edde02946d0d475221f2b2054d3d8ba upstream.
+
+If kmemdup() fails while copying supported band structures, the error
+path jumps to fail_rate. This skips rate_control_deinitialize() and
+leaks the initialized local->rate_ctrl.
+
+Fix this by adding a fail_band label that shares the rate-control cleanup
+path before falling through to the remaining teardown.
+
+The bug was first flagged by an experimental analysis tool we are
+developing for kernel memory-management bugs while analyzing
+v6.13-rc1. The tool is still under development and is not yet publicly
+available. Manual inspection confirms that the bug is still present in
+v7.1-rc7.
+
+An x86_64 allyesconfig build showed no new warnings. As we do not have a
+suitable mac80211 device/driver combination to test with, no runtime
+testing was able to be performed.

+Subject: wifi: rt2x00: avoid full teardown before work setup in probe
+
+From: Runyu Xiao <runyu.xiao@seu.edu.cn>
+
+commit 536fb3d739d75a03cb318c0c6fe799425cfea501 upstream.
+
+rt2x00lib_probe_dev() uses the full rt2x00lib_remove_dev() teardown for
+all probe failures. However, drv_data allocation and workqueue allocation
+can fail before intf_work, autowakeup_work and sleep_work have been
+initialized.
+
+Do not enter the full remove path until the probe has reached the point
+where those work items are set up. Return directly for drv_data allocation
+failure, and use a small early cleanup path for workqueue allocation
+failure.
+
+This issue was found by our static analysis tool and then confirmed by
+manual review of rt2x00lib_probe_dev() and rt2x00lib_remove_dev(). The
+early probe exits should not call a common teardown path that assumes the
+later work setup has already completed.
+
+A QEMU PoC forced alloc_ordered_workqueue() to fail before the work
+initializers are reached. The resulting fail path entered
+rt2x00lib_remove_dev(), and DEBUG_OBJECTS reported invalid work drains with
+rt2x00lib_probe_dev() and rt2x00lib_remove_dev() in the stack.
