CVE-2026-89538

CVE-2026-89538 affects the Linux kernel's SUNRPC component, specifically the gss_krb5_unwrap_v2() function. A remote peer holding a valid GSS context can send a Kerberos v2 wrap token whose 16-bit "extra count" (ec) field exceeds the plaintext length—a structurally malformed token per RFC 4121 . ...

CVE-2026-80955

CVE-2026-80955 is a use-after-free vulnerability in the Linux kernel's dm-pcache module, within the kset_replay() function. When a key's segment generation (key->seg_gen) is stale, cache_key_put(key) frees the key memory, but key->cache_pos.cache_seg is subsequently accessed as an argument ...
