Linux Distros Unpatched Vulnerability : CVE-2026-53335

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - mm/damon/lrusort: handle ctx allocation failure DAMONLRUSORT allocates the damonctx object for its kdamond in its init function. damonlrusortenabledstore wrongl...

CVE-2026-53334

A flaw was found in the Linux kernel's Data Access Monitor DAMON reclaim and Least Recently Used LRU sort mechanisms. This vulnerability arises from an incorrect assumption that a memory allocation will always succeed. If the allocation fails, a NULL pointer is dereferenced, which can lead to...

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 ...
