CVE-2023-53246

CVE-2023-53246 (Linux kernel, CIFS DFS upcall) : When CONFIG_CIFS_DFS_UPCALL is disabled, cifs_dfs_d_automount becomes NULL and the CIFS DFS referral handling can trigger a NULL pointer dereference in VFS follow_automount() while traversing a DFS referral. The fix adds an inline cifs_dfs_d_automo...

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-2023-53387

In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix device management cmd timeout flow In the UFS error handling flow, the host will send a device management cmd(NOP OUT) to the device for link recovery.

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-2023-53403

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-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-2026-31580

CVE-2026-31580 affects the Linux kernel (bcache component). The issue is a use-after-free in cached_dev.sb_bio when a device is stopped while a superblock write is in progress, which can cause a crash/DoS through libceph I/O paths. Public reports align on this being resolved by patching bcache to...

CVE-2026-31581

CVE-2026-31581 affects the Linux kernel ALSA 6fire USB audio driver. The issue is a use-after-free in usb6fire_chip_abort() where the chip structure is allocated as the card’s private data and, after snd_card_free_when_closed() frees the card (when no file handles are open), a later write to chip...

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-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-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-2023-53215

CVE-2023-53215 affects the Linux kernel sched/fair component. The issue occurs when the load balancer tries to migrate a task that is migration-disabled to its current CPU, triggering a warning in set_task_cpu() during balance. The root cause is how the new_dst_cpu is selected from env->dst_gr...

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-2026-31609

CVE-2026-31609 affects the Linux kernel SMB client; the double-free occurs in smbd_free_send_io() after smbd_send_batch_flush() because smbd_send_batch_flush() already frees via smbd_free_send_io() and has been moved to the batch list. The issue has been addressed in multiple advisories and patch...

CVE-2026-31583

The CVE-2026-31583 issue affects the Linux kernel em28xx media driver. A race in em28xx_v4l2_open() occurs because dev->v4l2 is read without holding dev->lock, racing with em28xx_v4l2_init()/em28xx_v4l2_fini() that free the structure and set dev->v4l2 to NULL under lock. This leads to us...

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).
