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...

CVE-2026-31635

CVE-2026-31635 affects the Linux kernel rxrpc component. The vulnerability stems from an inverted length check in rxgk_verify_response(), where oversized RESPONSE authenticators can be accepted and later cause a contradictory length that leads to a BUG_ON(len) in skb_to_sgvec(). This can crash th...
