CVE-2026-45874

CVE-2026-45874 affects the Linux kernel component under the phosphate path for Freescale IMX8QM HSIO. The issue arises when the devicetree provides no fsl,refclk-pad-mode; during probe, refclk_pad is set to NULL, and imx_hsio_configure_clk_pad() uses this pointer unconditionally, risking a NULL p...

CVE-2026-43020

CVE-2026-43020 concerns the Linux kernel Bluetooth MGMT path: load-time Long Term Keys can overflow a fixed-size stack buffer if enc_size exceeds the 16-byte key buffer. The root cause is validation of enc_size not rejecting oversized values during management LTK record validation, allowing inval...

CVE-2026-43048

The CVE concerns the Linux kernel HID core. The issue arises in hid_report_raw_event() where a memset() intended to clear bogus data can trigger out-of-bounds reads/writes when the incoming event buffer is not large enough for the report. The fix removes the problematic memset() and instead retur...

CVE-2026-43061

CVE-2026-43061 (Linux kernel): The serial8250 TX DMA deadlock was fixed. The root cause was that dmaengine_terminate_async did not guarantee the __dma_tx_complete callback would run, and that callback is the only place where dma->tx_running is cleared. If a TX DMA transaction is canceled and t...

CVE-2026-43073

CVE-2026-43073 stems from a misnamed x86-64 kernel routine __copy_user_nocache(), a non-temporal destination copy with exception handling that is not actually a pure user-kernel copy and has complex alignment behavior. The fix renames the function and normalizes the prototype so callers perform p...

CVE-2026-43088

CVE-2026-43088 (Linux kernel) affects PF_KEY export paths in the net: af_key code, where IPv6 sockaddr payloads were not fully initialized in certain export messages (SADB_ACQUIRE, SADB_X_NAT_T_NEW_MAPPING, SADB_X_MIGRATE). The issue arises because pfkey_sockaddr_size() reserves 32 bytes for IPv6...

CVE-2026-46151

CVE-2026-46151 affects the Linux kernel USB printer driver usblp, causing a heap leak in IEEE 1284 device ID handling due to short GET_DEVICE_ID responses. The issue stems from usblp_ctrl_msg() discarding actual bytes and usblp_cache_device_id_string() trusting a 2‑byte length prefix, exposing st...

CVE-2026-46161

CVE-2026-46161 affects the Linux kernel md/raid10 code: setup_geo() may divide by zero when fc (far copies) is 0, since it derives geo->far_set_size from disks/fc without validating zero. The fix validates nc and fc after extraction and returns -1 if either is zero. Connected OSV entries show ...

CVE-2026-46204

CVE-2026-46204 affects the Linux kernel DRM_AMDGPU driver (drm/amdgpu/vcn4). The root cause is an out-of-bounds read when parsing an Instruction Buffer (IB). The patch rewrites the IB parsing to use amdgpu_ib_get_value(), ensuring bounds checks are performed and preventing OOB reads. Public descr...

CVE-2026-46223

The CVE-2026-46223 issue concerns the Linux kernel cgroup subsystem: rmdir defers percpu_ref kill of CSS until the cgroup is depopulated. A chain of commits reworked rmdir behavior to ensure ->css_offline() does not run while tasks are still doing kernel work in the cgroup. The core problem wa...

CVE-2026-46229

The CVE-2026-46229 issue affects the Linux kernel’s DRM/AMDKFD path: KFD VRAM allocations could leave stale data because AMDGPU_GEM_CREATE_VRAM_CLEARED was not applied in the KFD code path, unlike the GEM/user paths which already set VRAM_CLEARED. This allowed stale page-table remnants to leak in...

CVE-2026-46279

CVE-2026-46279 — In the Linux kernel, the issue lies in mm/alloc_tag where pages allocated before page_ext initialization may have an uninitialized codetag, potentially triggering KASAN warnings when later freed.

CVE-2022-50307

In CVE-2022-50307, the Linux kernel s390/cio subsystem had an out-of-bounds read during cio_ignore free scans. The bug arose from an optimization that excluded online devices from scans, incorrectly assuming I/O-subchannel drvdata pointed to a private struct, which is invalid for devices bound to...

CVE-2022-50369

In CVE-2022-50369, the Linux kernel’s drm/vkms driver is affected by a null pointer dereference in vkms_release() when destroying the workqueue: vkms->output.composer_workq is destroyed after an OOM path allocates it later in vkms_crtc_init. The issue arises because vkms_release() can call des...

CVE-2023-53228

Summary: CVE-2023-53228 corresponds to a Linux kernel regression in the AMDGPU driver where, on command submission failure due to userptr invalidation, legacy code would redundantly clean up a scheduler job. The cleanup was unnecessary because the job cleanup logic was integrated into the existin...

CVE-2023-53232

CVE-2023-53232 affects the Linux kernel MT7921/MT76 stack. The vulnerability arises from a kernel panic due to accessing unallocated eeprom.data, leading to a NULL dereference in mt7921_mcu_parse_response. A fix is present: the MT7921 driver no longer uses eeprom.data, and the code referencing it...

CVE-2023-53266

The CVE-2023-53266 issue affects the Linux kernel (arm64) ACPI path involving ffh_ctxt allocation. The vulnerability arises when SMCCC version and conduit checks fail and a -EOPNOTSUPP return occurs without freeing the allocated ffh_ctxt memory, creating a memory leak. The documented fix moves th...

CVE-2023-53276

In CVE-2023-53276, the Linux kernel ubifs code leaks memory: fscrypt_setup_filename allocates memory for the tmpfile name, but this memory is not freed after the name is copied into the directory entry inode (ubifs_tmpfile → vfs_tmpfile → path_openat). The kmemleak report shows an unreferenced ob...

CVE-2023-53322

CVE-2023-53322 in the Linux kernel affects the scsi qla2xxx driver.

The connected advisories (EulerOS/RHEL) list this CVE among kernel f...

CVE-2023-53355

The CVE-2023-53355 entry concerns the Linux kernel (staging: pi433) where a memory leak occurs when using debugfs_lookup() because the returned object is not paired with dput(). The recommended fix is to use debugfs_lookup_and_remove(), which handles the necessary dput() logic and related cleanup...

CVE-2023-53360

CVE-2023-53360 affects the Linux kernel NFSv4.2 path for READ_PLUS and can cause a hole-decode oops and scratch buffer NULL/length mismatch due to reworked scratch handling that reused an nfs_pgio_header across multiple requests. The root cause is that multiple reads could be sent with a single n...

CVE-2023-53416

CVE-2023-53416 affects the Linux kernel USB isp1362 driver. The issue is a memory leak caused by calling debugfs_lookup() without releasing the result with dput(), allowing leaked memory over time. The fix simplifies the handling by using debugfs_lookup_and_remove(), which performs the lookup and...

CVE-2023-53431

The CVE-2023-53431 entry concerns Linux kernel SCSI SES: the fix ensures graceful handling when an enclosure has a primary component but no secondary components. Previously, devices with one primary enclosure and zero secondary enclosures could cause ses_intf_add() to bail, potentially triggering...

CVE-2023-53569

The CVE-2023-53569 entry refers to the Linux kernel ext2 filesystem check during mount, where the log of the block size stored in the superblock must be validated to prevent an overflow in the block size calculation. This vulnerability can cause undefined behavior if the block size value is not s...

CVE-2025-38243

The CVE-2025-38243 issue affects the Linux kernel’s Btrfs log replay path. In several locations that call read_one_inode(), a NULL inode pointer could be dereferenced (e.g., iput(&inode->vfs_inode) in __add_inode_ref()), causing an invalid memory access and a crash. The available connected doc...

CVE-2025-38309

CVE-2025-38309 affects the Linux kernel’s drm/xe/vm path. The root cause is that during vm creation, the code may call xe_svm_fini() on the error path before the SVM state is initialised, causing kernel splats and a fatal NPD. A fix moves xe_svm_init() earlier in xe_svm lifecycle to ensure proper...

CVE-2025-38370

CVE-2025-38370 concerns a Linux kernel issue in the BTRFS free-space-tree rebuild path. When rebuilding the free-space tree, allocating a new metadata block group could trigger multiple transactions; during the rebuild, btrfs_rebuild_free_space_tree() may encounter newly inserted block groups and...

CVE-2025-38394

The CVE-2025-38394 issue is in the Linux kernel HID path (appletkd/b appletb-kbd) where an input handler is registered to input core and then, if probe fails, freed memory remains in input_handler_list. This creates a use‑after‑free condition (UAF) in input_attach_handler during subsequent device...

CVE-2025-38411

CVE-2025-38411 affects the Linux kernel netfs code. The issue is a double put of the netfs request during cleanup: when a request finishes in the pause loop, the ref for IN_PROGRESS is removed, but the final wait loop may also call the collector if IN_PROGRESS is clear. The fix makes netfs_collec...
