CVE-2026-53023
CVE-2026-53023 in the Linux kernel affects the ntfs3 filesystem driver: when converting on-disk volume labels from UTF-16 to UTF-8, the cached label in sbi->volume.label is not guaranteed to be NUL-terminated, which could lead to reading past the buffer in ntfs3_label_show(). The fix explicitl...
CVE-2026-53053
The CVE-2026-53053 issue lies in the Linux kernel’s iommu/amd driver where clone_alias() incorrectly uses the wrong device ID (devid) for alias devices, risking propagation of wrong or stale Device Table Entries (DTEs). The fix passes the original pdev as opaque data to both clone_alias() and pci...

CVE-2026-53164
The CVE-2026-53164 entry concerns the Linux kernel IOMMU DMA SWIOTLB path. The vulnerability arises when iommu_dma_iova_link_swiotlb() maps an unaligned memory region and, if the middle portion is empty, calls iommu_map() with a 0 size, which the iommu_pt implementation treats as illegal, corrupt...
CVE-2026-53173
Summary (concrete details from provided docs): The Linux kernel component accel/ethosu contains an OOB write in ethosu_gem_cmdstream_copy_and_validate(). A local user can trigger by supplying a crafted command stream, causing memory corruption and potential instability. The issue arises in a pars...
CVE-2026-53234
The CVE-2026-53234 entry concerns the Linux kernel IBM EMAC network driver. The root cause is a use-after-free window created by using devm_register_netdev(), which defers unregister_netdev() to the devres cleanup phase after emac_remove() returns, allowing the network stack to access freed hardw...
CVE-2026-53237
In CVE-2026-53237, the Linux kernel’s mvebu GPIO implementation can dereference a NULL mvchip->mvpwm during suspend/resume because mvebu_pwm_suspend() / mvebu_pwm_resume() are invoked for all GPIO banks, including those without PWM functionality. The root cause is that some banks have mvchip-&...
CVE-2026-53298
In CVE-2026-53298, the Linux kernel airoha network driver is affected by a race in initialization: ndesc is initialized too early in airoha_qdma_init_rx_queue(), causing a NULL pointer dereference during cleanup if allocation fails. The documented fix moves ndesc initialization to the end of airo...
CVE-2026-53305
CVE-2026-53305 affects the Linux kernel USB Type-C ps883x driver. A NULL pointer dereference Oops occurs when unbinding a device for vfio-platform binding (example using unbind on bc0000.geniqup), caused by ps883x_retimer_remove() reading driver data via i2c_get_clientdata() that was never set du...
CVE-2026-53306
CVE-2026-53306 affects the Linux kernel tty/hvc_iucv path. The issue is an off-by-one in the number of supported devices: MAX_HVC_IUCV_LINES is 8, and hvc_iucv_devices can be 0–8. When devices == 8, a path that validates against the table size can access hvc_iucv_table[8], potentially triggering ...
CVE-2026-53308
The CVE-2026-53308 issue concerns the Linux kernel max77705 power supply driver. The root cause is improper management of a workqueue and interrupt handlers during device removal, which could lead to use-after-free of memory after the workqueue is destroyed but before the interrupt is freed via t...
CVE-2026-53317
CVE-2026-53317 concerns the Linux kernel wifi driver stack (mt76/mt7921). A station AID value greater than 20 could trigger a firmware crash on AP interfaces (IFTYPE_AP) when a modified hostapd allocates AIDs starting at a high value (65 in testing). The issue is mitigated by a fix that imposes a...

CVE-2026-53402
The CVE-2026-53402 issue affects the Linux kernel’s fbdev/fbcon path. When fbcon_do_set_font() fails (e.g., vc_resize() under memory pressure), the error path (err_out) only rolls back vc_font.charcount and neglects to restore hi_font state and the screen buffer. This leaves vc_hi_font_mask set, ...
CVE-2026-63806
CVE-2026-63806 relates to the Linux kernel KVM ioeventfd datamatch bug. The issue occurs when a guest store spans multiple pages and hits MMIO on the second page, potentially triggering a datamatch IO event due to an alignment check in a 32-byte destination pointer; the code used a BUG_ON() with ...
CVE-2026-64044
Concrete details confirm CVE-2026-64044 fix in the Linux kernel’s OpenVPN peer handling. The error path in ovpn_nl_peer_new_doit() previously called ovpn_peer_release() directly instead of ovpn_peer_put(), bypassing the kref, risking use-after-free when a caller holds a ref during an in-flight op...

CVE-2026-64147
The pds_core kernel driver leaks a dentry reference (missing dput()) on every firmware reset recovery, and when CONFIG_DEBUG_FS is disabled, debugfs_lookup() returns ERR_PTR(-ENODEV) rather than NULL, which the existing check passes, causing a crash. Red Hat confirms this can lead to denial of se...
CVE-2026-64234
The CVE-2026-64234 entry concerns the Linux kernel tty/serial driver pch_uart. The root cause is a missing check of the return value from dma_alloc_coherent(), which could yield a NULL pointer, triggering a crash in dma_handle_rx(). The fix adds a guard for dma_alloc_coherent() failure and ensure...
CVE-2026-64346
CVE-2026-64346 is a Use-After-Free (UAF) in the Linux kernel's USB gadget UDC subsystem. A race condition allows usb_del_gadget() to free the udc management structure (e.g., via a mode-switch workqueue) while gadget_match_driver() concurrently accesses it through configfs, triggering a NULL point...
CVE-2026-64387
Summary (CVE-2026-64387) : The Linux kernel SMB client is affected by a replay-double-free condition in query directory handling. If SMB2_query_directory_init() fails before the next send, a previously freed response buffer could be freed again due to stale bookkeeping, potentially compromising c...
CVE-2026-64402
CVE-2026-64402 concerns the Linux kernel coresight ultrasoc-smb path: an OOB write in smb_sync_perf_buffer() can occur when the SMB sink is used as a perf AUX sink because the initial page index is derived before applying modulo normalization to the buffer size. The issue is fixed by normalizing ...
CVE-2022-49992
This CVE (CVE-2022-49992) concerns the Linux kernel, where a swap-entry PFN fetch path could be misapplied during mprotect changes.

CVE-2022-50499
Linux kernel (media/dvb-core) contains a double free in dvb_register_device() when dvb_create_media_entity() fails and the caller frees dvb->entity again via dvb_media_device_free(), potentially causing a Use After Free in media_device_unregister_entity(). The fix, as described in CVE-2022-504...
CVE-2022-50513
CVE-2022-50513 affects Linux kernel staging/rtl8723bs: in the rtw_init_cmd_priv() error paths, pcmdpriv->cmd_allocated_buf was not freed when rsp_allocated_buf was allocated, causing a memory leak. The fix adds kfree(pcmdpriv->cmd_allocated_buf) on the error path and simplifies the return l...
CVE-2022-50532
CVE-2022-50532 concerns the Linux kernel SCSI MPT3sas driver. The vulnerability occurs in mpt3sas_transport_port_add(): if sas_rphy_add() returns an error, the resource allocated in sas_end_device_alloc() must be freed via sas_rphy_free(); otherwise a NULL pointer dereference can occur during dev...
CVE-2022-50542
CVE-2022-50542 affects the Linux kernel media/si470x driver. A use-after-free occurs in si470x_int_in_callback() when urb->context (holding a si470x_device) is freed if si470x_start_usb() has submitted a URB but the subsequent si470x_start() path fails. The fix ensures URBs are destroyed when ...
CVE-2022-50549
CVE-2022-50549 describes an ABBA deadlock in the Linux kernel’s dm-thin path where concurrent drop_caches and dm thin worker activity can cause a deadlock between shrink_slab (holding shrinker_rwsem) and dm_pool_abort_metadata (holding dm_block/root locks). The result is a hung task as shown by t...
CVE-2023-53171
CVE-2023-53171 affects the Linux kernel’s vfio/type1 path. The issue occurs when a vfio container is preserved across execs: the task’s mm can change to a new mm with locked_vm=0, causing undercounted DMA mappings and a later unmap to underflow locked_vm, leading to ENOMEM on a subsequent dma map...
CVE-2023-53207
CVE-2023-53207 applies to the Linux kernel ublk subsystem. The issue arises in ublk_ctrl_end_recovery: if wait_for_completion_interruptible() is interrupted by a signal, queues aren’t yet fully set up, so the kernel must fail UBLK_CMD_END_USER_RECOVERY to avoid a kernel oops. The CVSS 3.1 data in...
CVE-2023-53217
Summary (CVE-2023-53217): Linux kernel vulnerability affecting the nubus subsystem where reading files under /proc/bus/nubus could segfault.
