CVE-2026-31640

CVE-2026-31640 affects the Linux kernel rxrpc component. The issue occurs in rxrpc_post_response() where the code compares the challenge serial number using the newer packet private data instead of the cached/older response, causing the comparison to always be false and potentially preventing the...

CVE-2026-31636

Summary: CVE-2026-31636 affects the Linux kernel rxrpc subsystem. The root cause is in rxgk_verify_authenticator(), which copies auth_len into a temporary buffer and then uses p + auth_len as the parser limit. Because p is a __be32*, this inflates the parser end pointer by four, enabling a slab-o...
