| In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: add peer map clean up for peer delete in ath10k_sta_state() When peer delete failed in a disconnect operation, use-after-free detected by KFENCE in below log. It is because for each vdev_id and address, it has only one struct ath10k_peer, it is allocated in ath10k_peer_map_event(). When connected to an AP, it has more than one HTT_T2H_MSG_TYPE_PEER_MAP reported from firmware, then the array peer_map of struct ath10k will be set muti-elements to the same ath10k_peer in ath10k_peer_map_event(). When peer delete failed in ath10k_sta_state(), the ath10k_peer will be free for the 1st peer id in array peer_map of struct ath10k, and then use-after-free happened for the 2nd peer id because they map to the same ath10k_peer. And clean up all peers in array peer_map for the ath10k_peer, then user-after-free disappeared peer map event log: [ 306.911021] wlan0: authenticate with b0:2a:43:e6:75:0e [ 306.957187] ath10k_pci 0000:01:00.0: mac vdev 0 peer create b0:2a:43:e6:75:0e (new sta) sta 1 / 32 peer 1 / 33 [ 306.957395] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 246 [ 306.957404] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 198 [ 306.986924] ath10k_pci 0000:01:00.0: htt peer map vdev 0 peer b0:2a:43:e6:75:0e id 166 peer unmap event log: [ 435.715691] wlan0: deauthenticating from b0:2a:43:e6:75:0e by local choice (Reason: 3=DEAUTH_LEAVING) [ 435.716802] ath10k_pci 0000:01:00.0: mac vdev 0 peer delete b0:2a:43:e6:75:0e sta ffff990e0e9c2b50 (sta gone) [ 435.717177] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 246 [ 435.717186] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 198 [ 435.717193] ath10k_pci 0000:01:00.0: htt peer unmap vdev 0 peer b0:2a:43:e6:75:0e id 166 use-after-free log: [21705.888627] wlan0: deauthenticating from d0:76:8f:82:be:75 by local choice (Reason: 3=DEAUTH_LEAVING) [21713.799910] ath10k_pci 0000:01:00.0: failed to delete peer d0:76:8f:82:be:75 for vdev 0: -110 [21713.799925] ath10k_pci 0000:01:00.0: found sta peer d0:76:8f:82:be:75 (ptr 0000000000000000 id 102) entry on vdev 0 after it was supposedly removed [21713.799968] ================================================================== [21713.799991] BUG: KFENCE: use-after-free read in ath10k_sta_state+0x265/0xb8a [ath10k_core] [21713.799991] [21713.799997] Use-after-free read at 0x00000000abe1c75e (in kfence-#69): [21713.800010] ath10k_sta_state+0x265/0xb8a [ath10k_core] [21713.800041] drv_sta_state+0x115/0x677 [mac80211] [21713.800059] __sta_info_destroy_part2+0xb1/0x133 [mac80211] [21713.800076] __sta_info_flush+0x11d/0x162 [mac80211] [21713.800093] ieee80211_set_disassoc+0x12d/0x2f4 [mac80211] [21713.800110] ieee80211_mgd_deauth+0x26c/0x29b [mac80211] [21713.800137] cfg80211_mlme_deauth+0x13f/0x1bb [cfg80211] [21713.800153] nl80211_deauthenticate+0xf8/0x121 [cfg80211] [21713.800161] genl_rcv_msg+0x38e/0x3be [21713.800166] netlink_rcv_skb+0x89/0xf7 [21713.800171] genl_rcv+0x28/0x36 [21713.800176] netlink_unicast+0x179/0x24b [21713.800181] netlink_sendmsg+0x3a0/0x40e [21713.800187] sock_sendmsg+0x72/0x76 [21713.800192] ____sys_sendmsg+0x16d/0x1e3 [21713.800196] ___sys_sendmsg+0x95/0xd1 [21713.800200] __sys_sendmsg+0x85/0xbf [21713.800205] do_syscall_64+0x43/0x55 [21713.800210] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [21713.800213] [21713.800219] kfence-#69: 0x000000009149b0d5-0x000000004c0697fb, size=1064, cache=kmalloc-2k [21713.800219] [21713.800224] allocated by task 13 on cpu 0 at 21705.501373s: [21713.800241] ath10k_peer_map_event+0x7e/0x154 [ath10k_core] [21713.800254] ath10k_htt_t2h_msg_handler+0x586/0x1039 [ath10k_core] [21713.800265] ath10k_htt_htc_t2h_msg_handler+0x12/0x28 [ath10k_core] [21713.800277] ath10k_htc_rx_completion_handler+0x14c/0x1b5 [ath10k_core] [21713.800283] ath10k_pci_process_rx_cb+0x195/0x1d ---truncated--- | ||||
| CVE-2022-50576 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: serial: pch: Fix PCI device refcount leak in pch_request_dma() As comment of pci_get_slot() says, it returns a pci_device with its refcount increased. The caller must decrement the reference count by calling pci_dev_put(). Since 'dma_dev' is only used to filter the channel in filter(), we can call pci_dev_put() before exiting from pch_request_dma(). Add the missing pci_dev_put() for the normal and error path. | ||||

| CVE-2023-53706 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: mm/vmemmap/devdax: fix kernel crash when probing devdax devices commit 4917f55b4ef9 ("mm/sparse-vmemmap: improve memory savings for compound devmaps") added support for using optimized vmmemap for devdax devices. But how vmemmap mappings are created are architecture specific. For example, powerpc with hash translation doesn't have vmemmap mappings in init_mm page table instead they are bolted table entries in the hardware page table vmemmap_populate_compound_pages() used by vmemmap optimization code is not aware of these architecture-specific mapping. Hence allow architecture to opt for this feature. I selected architectures supporting HUGETLB_PAGE_OPTIMIZE_VMEMMAP option as also supporting this feature. This patch fixes the below crash on ppc64.

| In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: skip splitting and logical rewriting on pre-alloc write When doing a relocation, there is a chance that at the time of btrfs_reloc_clone_csums(), there is no checksum for the corresponding region. In this case, btrfs_finish_ordered_zoned()'s sum points to an invalid item and so ordered_extent's logical is set to some invalid value. Then, btrfs_lookup_block_group() in btrfs_zone_finish_endio() failed to find a block group and will hit an assert or a null pointer dereference as following. This can be reprodcued by running btrfs/028 several times (e.g, 4 to 16 times) with a null_blk setup. The device's zone size and capacity is set to 32 MB and the storage size is set to 5 GB on my setup.

| In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Clean up only new IRQ glue on request_irq() failure The mlx5_irq_alloc() function can inadvertently free the entire rmap and end up in a crash[1] when the other threads tries to access this, when request_irq() fails due to exhausted IRQ vectors. This commit modifies the cleanup to remove only the specific IRQ mapping that was just added. This prevents removal of other valid mappings and ensures precise cleanup of the failed IRQ allocation's associated glue object. Note: This error is observed when both fwctl and rds configs are enabled.

| In the Linux kernel, the following vulnerability has been resolved: nilfs2: avoid having an active sc_timer before freeing sci Because kthread_stop did not stop sc_task properly and returned -EINTR, the sc_timer was not properly closed, ultimately causing the problem [1] reported by syzbot when freeing sci due to the sc_timer not being closed. Because the thread sc_task main function nilfs_segctor_thread() returns 0 when it succeeds, when the return value of kthread_stop() is not 0 in nilfs_segctor_destroy(), we believe that it has not properly closed sc_timer. We use timer_shutdown_sync() to sync wait for sc_timer to shutdown, and set the value of sc_task to NULL under the protection of lock sc_state_lock, so as to avoid the issue caused by sc_timer not being properly shutdowned.

| CVE-2025-40007 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfs: fix reference leak Commit 20d72b00ca81 ("netfs: Fix the request's work item to not require a ref") modified netfs_alloc_request() to initialize the reference counter to 2 instead of 1. The rationale was that the requet's "work" would release the second reference after completion (via netfs_{read,write}_collection_worker()). That works most of the time if all goes well. However, it leaks this additional reference if the request is released before the I/O operation has been submitted: the error code path only decrements the reference counter once and the work item will never be queued because there will never be a completion. This has caused outages of our whole server cluster today because tasks were blocked in netfs_wait_for_outstanding_io(), leading to deadlocks in Ceph (another bug that I will address soon in another patch). This was caused by a netfs_pgpriv2_begin_copy_to_cache() call which failed in fscache_begin_write_operation(). The leaked netfs_io_request was never completed, leaving `netfs_inode.io_count` with a positive value forever. All of this is super-fragile code. Finding out which code paths will lead to an eventual completion and which do not is hard to see: - Some functions like netfs_create_write_req() allocate a request, but will never submit any I/O. - netfs_unbuffered_read_iter_locked() calls netfs_unbuffered_read() and then netfs_put_request(); however, netfs_unbuffered_read() can also fail early before submitting the I/O request, therefore another netfs_put_request() call must be added there. A rule of thumb is that functions that return a `netfs_io_request` do not submit I/O, and all of their callers must be checked. For my taste, the whole netfs code needs an overhaul to make reference counting easier to understand and less fragile & obscure. But to fix this bug here and now and produce a patch that is adequate for a stable backport, I tried a minimal approach that quickly frees the request object upon early failure. I decided against adding a second netfs_put_request() each time because that would cause code duplication which obscures the code further. Instead, I added the function netfs_put_failed_request() which frees such a failed request synchronously under the assumption that the reference count is exactly 2 (as initially set by netfs_alloc_request() and never touched), verified by a WARN_ON_ONCE(). It then deinitializes the request object (without going through the "cleanup_work" indirection) and frees the allocation (with RCU protection to protect against concurrent access by netfs_requests_seq_start()). All code paths that fail early have been changed to call netfs_put_failed_request() instead of netfs_put_request(). Additionally, I have added a netfs_put_request() call to netfs_unbuffered_read() as explained above because the netfs_put_failed_request() approach does not work there. | ||||
