{"id":"DEBIAN-CVE-2024-49944","details":"In the Linux kernel, the following vulnerability has been resolved:  sctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start  In sctp_listen_start() invoked by sctp_inet_listen(), it should set the sk_state back to CLOSED if sctp_autobind() fails due to whatever reason.  Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)-\u003ereuse is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)-\u003ebind_hash will be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash is NULL.
