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...

Technical details for CVE-2026-64103 are not publicly available in the provided documents. Monitor for updates.

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-2022-50454

CVE-2022-50454 affects the Linux kernel’s DRM Nouveau driver. The vulnerability arises in nouveau_gem_prime_import_sg_table() due to a use-after-free: on failure of nouveau_bo_init(), the associated gem object is released by ttm_bo_init(), but the code later calls nouveau_bo_ref() which dereferen...

CVE-2022-50460

The CVE-2022-50460 issue is in the Linux kernel CIFS logic: an xid leak in cifs_flock() when flock is used can leak xid on early return (-ENOLCK).

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.

CVE-2023-53341

CVE-2023-53341 refers to a Linux kernel memory initialization fix: the function early_init_dt_scan_memory now returns 1 when memory is found and 0 if none, allowing other memory setup paths to run. This changes the control flow after the ramips plat_mem_setup call, addressing scenarios where memo...

CVE-2023-53462

Summary: The CVE concerns the Linux kernel HID/HSR driver (net/hsr/hsr_forward.c). A KMSAN-uninitialized-value access is reported in fill_frame_info() when VLAN (ETH_P_8021Q) is encountered, due to VLAN not being supported in the hsr driver.
