Current Description

net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before does not verify that the SCTP-AUTH extension is enabled before proceeding with SCTP-AUTH API functions, which allows attackers to cause a denial of service (NULL pointer dereference and panic) via vectors that result in calls to (1) sctp_setsockopt_auth_chunk, (2) sctp_setsockopt_hmac_ident, (3) sctp_setsockopt_auth_key, (4) sctp_setsockopt_active_key, (5) sctp_setsockopt_del_key, (6) sctp_getsockopt_maxburst, (7) sctp_getsockopt_active_key, (8) sctp_getsockopt_peer_auth_chunks, or (9) sctp_getsockopt_local_auth_chunks.
