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 ...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...
