CVE-2026-31575

The CVE-2026-31575 issue affects the Linux kernel mm/userfaultfd code, where hugetlb fault mutex hashing used linear_page_index() (PAGE_SIZE units) instead of huge-page units, causing different mutexes to be used for addresses within the same huge page. The mismatch can allow races between faulti...

CVE-2022-50314

The CVE-2022-50314 issue affects the Linux kernel nbd subsystem. When a signal interrupts nbd_start_device_ioctl() while waiting for inflight I/Os to complete, a hung task could occur. The fix clears the queue (not just shutdown) on signal interruption to nbd_start_device_ioctl(), mitigating the ...

CVE-2022-50315

CVE-2022-50315: Linux kernel ata: ahci: Match EM_MAX_SLOTS with SATA_PMP_MAX_PORTS. The issue arises when sata_pmp_init_links() initializes link->pmp up to SATA_PMP_MAX_PORTS while em_priv is an 8-element array, causing a UBSAN array-index-out-of-bounds in libahci.c. The patch aligns EM_MAX_SL...

CVE-2022-50359

CVE-2022-50359 affects Linux kernel media driver cx88: null-ptr-deref in buffer_prepare() when cx88_risc_buffer() fails, leading to empty buffer and null-ptr-deref in buffer_queue(). The issue is fixed by validating the return value of cx88_risc_buffer() before use. Affected reports in connected ...

CVE-2022-50379

CVE-2022-50379 involves the Linux kernel btrfs quota handling. The issue occurs during quota enabling: after committing the transaction, the quota_root is assigned and BTRFS_FS_QUOTA_ENABLED is set, then the code starts the qgroup rescan worker via qgroup_rescan_init(). If that init fails, the qu...

CVE-2023-53403

CVE-2023-53403: Linux kernel vulnerability in time/debug causing potential memory leak when using debugfs_lookup(). The issue arises because the result of debugfs_lookup() must be dput()-ed; if not, memory leaks occur over time. The documented mitigation is to replace the call with debugfs_lookup...

CVE-2023-53437

CVE-2023-53437 affects the Linux kernel media: uvcvideo driver. The vulnerability arises when handling cameras with invalid descriptors, potentially enabling local attacker access due to improper link handling when a source entity has no pads. Public docs (OpenVAS/Nessus summaries) list updates t...

CVE-2022-50274

CVE-2022-50274 : In the Linux kernel, a use-after-free in dvb_unregister_device() was mitigated by adding a reference counter to struct dvb_device and delaying deallocation until no pointers reference the object. The vulnerability stemmed from cleanup releasing the dvb_device while file->priva...

CVE-2022-50286

The CVE-2022-50286 issue affects the Linux kernel ext4 file system in scenarios where bigalloc and inline options are used simultaneously. The root cause is in ext4_clu_mapped: when converting inline-stored data to extents, the code may search the (non-existent) extent tree to decide if a block s...

CVE-2022-50293

CVE-2022-50293 affects the Linux kernel btrfs subsystem. When dropping file extent items for a range, ENOMEM could trigger a BUG_ON() path in btrfs_drop_extents(); the fix replaces those BUG_ON()s with proper transaction abort and error return handling. This means that instead of halting the tran...

CVE-2022-50250

CVE-2022-50250 — Linux kernel regulator core use_count leakage (boot-on) . The advisory describes a leakage where, when a regulator rdev (A) is boot-on, enabling its supply regulator (B) increments B’s use_count inside regulator_enable(rdev->supply). If B is also boot-on, it behaves as always-...

CVE-2023-53309

CVE-2023-53309 affects the Linux kernel’s drm/radeon path. The vulnerability stems from an overflow in radeon_cs_parser_init: the size field is unsigned, and if size equals 0x40000000, the calculation size *= sizeof(uint32_t) overflows, causing size to wrap to zero and leading to use of uninitial...

CVE-2023-53339

CVE-2023-53339 : In the Linux kernel’s Btrfs code, a race between pausing and balancing can cause a BUG_ON panic in btrfs_cancel_balance due to an unaccounted race. The race has no other side effects, and a fix has been applied in the upstream patch set. The vulnerability affects local attackers ...

CVE-2023-53390

CVE-2023-53390 affects the Linux kernel (drivers: base: dd) where a call to debugfs_lookup() leaked memory because the result wasn’t dput()-ed. The fix uses debugfs_lookup_and_remove() to handle lookup and cleanup atomically, preventing the leak. Impact described: potential unbounded memory growt...

CVE-2023-53395

The CVE-2023-53395 entry refers to ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer. The issue arises from ASL Timer instructions that require no argument; without AML_NO_OPERAND_RESOLVE, interpreting the Timer instruction could produce an error, and the fix adds AML_NO_OPERAND_RESOLVE to the Tim...

CVE-2026-31577

CVE-2026-31577 affects the Linux kernel nilfs2 filesystem. The vulnerability is a NULL i_assoc_inode dereference in nilfs_mdt_save_to_shadow_map during GC if NILFS_IOCTL_CLEAN_SEGMENTS is invoked immediately after mount, before any btree operation on the DAT inode. The root cause is i_assoc_inode...

CVE-2022-50306

CVE-2022-50306 concerns a Linux kernel issue in ext4 where ext4_fc_replay_scan() could perform an out-of-bounds read during journal scan if the remaining space is smaller than EXT4_FC_TAG_BASE_LEN. The root cause is insufficient bounds checking for the three journal scan tags (ADD_RANGE/HEAD/TAIL...

CVE-2023-53148

In CVE-2023-53148, the Linux kernel igb driver had a task-hang vulnerability when a Thunderbolt hub is unplugged. The igb_down path could be invoked twice (via igb_io_error_detected and igb_remove), causing a hang at napi_synchronize and breaking Ethernet. The patch prevents the non-fatal PCIe er...

CVE-2023-53182

Technical details about CVE-2023-53182 are not publicly provided in the supplied documents. Monitor for updates.

CVE-2023-53402

CVE-2023-53402 affects the Linux kernel, specifically the printk debugfs path. The root cause is a memory leak in kernel/printk/index.c when using debugfs_lookup() without a matching dput(). The documented fix replaces the sequence with debugfs_lookup_and_remove(), handling the logic and preventi...

CVE-2022-50366

CVE-2022-50366 affects the Linux kernel powercap subsystem (intel_rapl). Root cause: UBSAN shift-out-of-bounds when ilog2() is computed with a value

CVE-2023-53337

The CVE concerns the Linux kernel nilfs2 subsystem. After metadata corruption is detected, nilfs2 may degenerate to read-only mode and still perform log writes, causing mark_buffer_dirty() to be invoked on buffer heads lacking the uptodate flag. The vulnerability arises from writes to a read‑only...

CVE-2023-53244

In Linux kernel, the media: pci: tw68 driver vulnerability CVE-2023-53244 fixes a null pointer dereference in buffer handling: if dma_alloc_coherent fails during tw68_risc_buffer(), buf->cpu may be null and later accesses/free could crash. The fix adds checks on the return value of tw68_risc_b...

CVE-2022-50320

The CVE-2022-50320 issue is a Linux kernel ACPI FPDT FPDT table bug where invalid physical addresses trigger ioremap warnings and an oops. The root cause is calling acpi_os_map_memory() on an invalid phys address; a fix adds a validation step to prevent mapping invalid addresses. The description ...

CVE-2026-31584

CVE-2026-31584 - Linux kernel (MediaTek vcodec) use-after-free in encoder release path : The fops_vcodec_release() frees the context (ctx) without cancelling or synchronizing pending/running encode work, allowing the mtk_venc_worker to dereference freed ctx. Root cause: v4l2_m2m_ctx_release() wai...

CVE-2026-64212

CVE-2026-64212 concerns the Linux kernel’s iwlwifi driver, where in iwl_mld_remove_link a NULL pointer check was missing before dereferencing link->fw_id. The linked analysis shows the fw_id is saved at function entry, but the link pointer can be NULL when fw_id is stored, risking a use-after-...

CVE-2026-43131

CVE-2026-43131 affects the Linux kernel DRM AMD PM path. When SMU is disabled during Reliability, Availability, and Serviceability (RAS) initialization, a null pointer dereference can occur in drm/amd/pm, potentially causing a system crash (DoS). Public-availability details come from multiple sou...
