+Subject: audit: enforce AUDIT_LOCKED for AUDIT_TRIM and AUDIT_MAKE_EQUIV
+
+From: Sergio Correia <scorreia@redhat.com>
+
+commit f9e1c1324b4d98d591a6f7568fdebf5cf456dfc2 upstream.
+
+AUDIT_ADD_RULE and AUDIT_DEL_RULE correctly check for AUDIT_LOCKED
+and return -EPERM, but AUDIT_TRIM and AUDIT_MAKE_EQUIV do not. This
+allows a process with CAP_AUDIT_CONTROL to modify directory tree
+watches and equivalence mappings even when the audit configuration
+has been locked, undermining the purpose of the lock.
+
+Add AUDIT_LOCKED checks to both commands.

+Subject: audit: fix incorrect inheritable capability in CAPSET records
+
+From: Sergio Correia <scorreia@redhat.com>
+
+commit e4a640475e43f406fdfd56d370b1f34b0cbbc18d upstream.
+
+__audit_log_capset() records the effective capability set into the
+inheritable field due to a copy-paste error. Every CAPSET audit
+record therefore reports cap_pi (process inheritable) with the value
+of cap_effective instead of cap_inheritable.
+
+This silently corrupts audit data used for compliance and forensic
+analysis: an attacker who modifies inheritable capabilities to
+prepare for a privilege-escalating exec would have the change masked
+in the audit trail.
+
+The bug has been present since the original introduction of CAPSET
+audit records in 2008.
+
+Cc: stable@vger.kernel.org
+Fixes: e68b75a027bb ("When the capset syscall is used it is not possible for audit to record the actual capbilities being added/removed. This patch adds a new record type which emits the target pid and the eff, inh, and perm cap sets.")

+
+From: Guopeng Zhang <zhangguopeng@kylinos.cn>
+
+commit 796ad622040f7f955ccc3973085e953415920496 upstream.
+
+get_cg_pool_unlocked() handles allocation failures under dmemcg_lock by
+dropping the lock, preallocating a pool with GFP_KERNEL, and retrying the
+locked lookup and creation path.
+
+If the fallback allocation fails too, pool remains NULL. Since the loop
+condition is while (!pool), the function can keep retrying instead of
+propagating the allocation failure to the caller.
+
+Set pool to ERR_PTR(-ENOMEM) when the fallback allocation fails so the
+loop exits through the existing common return path. The callers already
+handle ERR_PTR() from get_cg_pool_unlocked(), so this restores the
+expected error path.

+From: Matt Vollrath <tactii@gmail.com>
+
+commit 678b713ece1e853f11e670a84cb887c35e1381b7 upstream.
+
+PTP pin structs are allocated early in probe, but never cleaned up.
+
+Fix this by calling i40e_ptp_free_pins in the error path.
+
+To support this, i40e_ptp_free_pins is added to the header and
+pin_config is correctly nullified after being freed.
+
+This has been an issue since i40e_ptp_alloc_pins was introduced.

+Subject: idpf: fix double free and use-after-free in aux device error paths
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+commit 6c77b9510829a424d1b74409b7db9456e3522871 upstream.
+
+When auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or
+idpf_plug_core_aux_dev(), the err_aux_dev_add label calls
+auxiliary_device_uninit() and falls through to err_aux_dev_init. The
+uninit call will trigger put_device(), which invokes the release
+callback (idpf_vport_adev_release / idpf_core_adev_release) that frees
+iadev. The fall-through then reads adev->id from the freed iadev for
+ida_free() and double-frees iadev with kfree().
+
+Free the IDA slot and clear the back-pointer before uninit, while adev
+is still valid, then return immediately.
+
+Commit 65637c3a1811 ("idpf: fix UAF in RDMA core aux dev deinitialization")
+fixed the same use-after-free in the matching unplug path in this file but
+missed both probe error paths.

+Subject: KVM: Reject wrapped offset in kvm_reset_dirty_gfn()
+
+From: Aaron Sacks <contact@xchglabs.com>
+
+commit 577a8d3bae0531f0e5ccfac919cd8192f920a804 upstream.
+
+kvm_reset_dirty_gfn() guards the gfn range with
+
+ if (!memslot || (offset + __fls(mask)) >= memslot->npages)
+ return;
+
+but offset is u64 and the addition is unchecked. The check can be
+silently bypassed by a u64 wrap.
+
+The dirty ring backing those entries is MAP_SHARED at
+KVM_DIRTY_LOG_PAGE_OFFSET of the vcpu fd, so the VMM can rewrite the
+slot and offset fields of any entry between when the kernel pushes
+them and when KVM_RESET_DIRTY_RINGS consumes them. On reset,
+kvm_dirty_ring_reset() re-reads the values via READ_ONCE() and feeds
+them straight back into this check; only the flags handshake is
+treated as the handover, the slot/offset payload is taken on trust.
+
+Crafting two entries
+
+ entry[i].offset = 0xffffffffffffffc1
+ entry[i+1].offset = 0
+
+makes the coalescing loop in kvm_dirty_ring_reset() compute
+
+ delta = (s64)(0 - 0xffffffffffffffc1) = 63
+
+which falls in [0, BITS_PER_LONG), so it folds entry[i+1] into the
+existing mask by setting bit 63. The trailing kvm_reset_dirty_gfn()
+call then sees offset = 0xffffffffffffffc1 and __fls(mask) = 63;
+the sum is 0 in u64 and the bounds check passes.
+
+That offset propagates into kvm_arch_mmu_enable_log_dirty_pt_masked()
+unchanged. On the legacy MMU path -- kvm_memslots_have_rmaps() ==
+true, i.e. shadow paging, any VM that has allocated shadow roots, or
+a write-tracked slot -- it reaches gfn_to_rmap(), which indexes
+slot->arch.rmap[0][] with a near-U64_MAX gfn. That is an
+out-of-bounds load of a kvm_rmap_head, followed by a conditional
+clear of PT_WRITABLE_MASK in whatever the loaded pointer points at.
+The path is reachable from any process holding /dev/kvm.
+
+Range-check offset on its own first, so the addition cannot wrap.
+memslot->npages is bounded well below U64_MAX, so once offset <
+npages holds, offset + __fls(mask) (with __fls(mask) < BITS_PER_LONG)
+stays in range.

+
+kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and

+
+Since aift->gait is already a struct zpci_gaite pointer, this

+Subject: net: atlantic: preserve PCI wake-from-D3 on shutdown when WOL enabled
+
+From: Zoran Ilievski <goodboy@rexbytes.com>
+
+commit 2c308cf34284420963607d677d576a2b4124d8bd upstream.
+
+The shutdown handler aq_pci_shutdown() unconditionally calls
+pci_wake_from_d3(pdev, false), clearing the PCI PME_En bit even when
+wake-on-LAN has been configured. While aq_nic_shutdown() correctly
+programs the NIC firmware via aq_nic_set_power() to listen for magic
+packets, the PCI subsystem will not propagate the resulting PME wake
+event from D3, so the system never wakes after poweroff.
+
+WOL from suspend (S3) is unaffected because aq_suspend_common() does
+not touch pci_wake_from_d3() and relies on the PM core's wake
+configuration via device_may_wakeup().
+
+This affects all atlantic-supported NICs (AQC107/108/111/112/113);
+users have reported that WOL works if the atlantic driver is never
+loaded, but breaks once it has run its shutdown path.
+
+Pass the configured WOL state to pci_wake_from_d3() instead of a
+literal false, so the PCI PME_En bit is preserved when the user has
+armed WOL via ethtool.

+Subject: net: ena: PHC: Check return code before setting timestamp output
+
+From: Arthur Kiyanovski <akiyano@amazon.com>
+
+commit 24a08d7d6218d60c033015cf4870b6096446e734 upstream.
+
+ena_phc_gettimex64() is setting the output parameter regardless
+of whether ena_com_phc_get_timestamp() succeeded or failed.
+
+When ena_com_phc_get_timestamp() returns an error, the timestamp
+parameter may contain uninitialized stack memory (e.g., when PHC is
+disabled or in blocked state) or invalid hardware values. Passing
+these to userspace via the PTP ioctl is both a security issue
+(information leak) and a correctness bug.
+
+Fix by checking the return code after releasing the lock and only
+setting the output timestamp on success.

+Subject: net: ena: PHC: Fix potential use-after-free in get_timestamp
+
+From: Arthur Kiyanovski <akiyano@amazon.com>
+
+commit e42c755582f0960e684298762f0ab927b3778376 upstream.
+
+Move the phc->active check and resp pointer assignment to after
+acquiring the spinlock. Previously, phc->active was checked without
+holding the lock, and resp was cached from ena_dev->phc.virt_addr
+before the lock was acquired.
+
+If ena_com_phc_destroy() runs between the lockless active check and
+the lock acquisition, it sets active=false, releases the lock, frees
+the DMA memory, and sets virt_addr=NULL. The get_timestamp path would
+then read a NULL virt_addr and dereference it.
+
+With both the active check and the pointer read under the lock,
+destroy cannot free the memory while get_timestamp is using it.

+From: Li Xiasong <lixiasong1@huawei.com>
+
+commit eb6317739b1ea3ab28791e1f91b24781905fa815 upstream.
+
+process_register_request() allocates an expectation and then checks
+whether a conntrack helper is available. If helper lookup fails, the
+function returns early and the allocated expectation is left behind.
+
+Reorder the code to fetch and validate helper before calling
+nf_ct_expect_alloc(). This keeps the logic simpler and removes the leak
+path while preserving existing behavior.

+Subject: workqueue: Fix wq->cpu_pwq leak in alloc_and_link_pwqs() WQ_UNBOUND path
+
+From: Breno Leitao <leitao@debian.org>
+
+commit 0143033dc22cdff912cfc13419f5db92fea3b4cb upstream.
+
+For WQ_UNBOUND workqueues, alloc_and_link_pwqs() allocates wq->cpu_pwq
+via alloc_percpu() and then calls apply_workqueue_attrs_locked(). On
+failure it returns the error directly, bypassing the enomem: label
+which holds the only free_percpu(wq->cpu_pwq) in this function.
+
+The caller's error path kfree()s wq without touching wq->cpu_pwq,
+leaking one percpu pointer table (nr_cpu_ids * sizeof(void *) bytes) per
+failed call.
+
+If kmemleak is enabled, we can see:
+
+ unreferenced object (percpu) 0xc0fffa5b121048 (size 8):
+ comm "insmod", pid 776, jiffies 4294682844

+ pcpu_alloc_noprof+0x665/0xac0
+ __alloc_workqueue+0x33f/0xa20
+ alloc_workqueue_noprof+0x60/0x100
+
+Route the error through the existing enomem: cleanup and any error
+before this one.
