CVE-2026-53348

CVE-2026-53348 affects the Linux kernel ASoC SDCA component. The root cause is a NULL pointer dereference in sdca_dev_unregister_functions where func_dev entries may be NULL if a registration failed early or a deferral race occurs during cleanup, leading to a kernel oops (device_del). The issue i...

CVE-2026-53335

The CVE-2026-53335 issue concerns the Linux kernel DAMON_LRU_SORT path (mm/damon/lru_sort). The root cause is damon_ctx allocation failure in the init path, which may lead to a NULL ctx passed to damon_commit_ctx() and a NULL pointer dereference. The documented fix is to return -ENOMEM if ctx is ...

CVE-2026-53334

The CVE-2026-53334 issue affects the Linux kernel DAMON subsystem, specifically mm/damon/reclaim and mm/damon/lru_sort. The root cause is a failure to handle damon_ctx allocations: if the kdamond damon_ctx allocation fails, code may dereference a NULL ctx in damon_commit_ctx(), leading to potenti...
