Summary
sctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start
Details

In the Linux kernel, the following vulnerability has been resolved:

sctp: set skstate back to CLOSED if autobind fails in sctplisten_start

In sctplistenstart() invoked by sctpinetlisten(), it should set the skstate back to CLOSED if sctpautobind() fails due to whatever reason.

Otherwise, next time when calling sctpinetlisten(), if sctpsk(sk)->reuse is already set via setsockopt(SCTPREUSEPORT), sctpsk(sk)->bindhash will be dereferenced as skstate is LISTENING, which causes a crash as bind_hash is NULL.

KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] RIP: 0010:sctpinetlisten+0x7f0/0xa20 net/sctp/socket.c:8617 Call Trace: <TASK> __syslistensocket net/socket.c:1883 [inline] __sys_listen+0x1b7/0x230 net/socket.c:1894 __dosyslisten net/socket.c:1902 [inline]
