Subject: CVE request: kernel: sctp: Fix kernel panic while process protocol
 violation parameter

This was committed in upstream kernel recently.

"[PATCH] sctp: Fix kernel panic while process protocol violation parameter

Since call to function sctp_sf_abort_violation() need paramter 'arg'
with 'struct sctp_chunk' type, it will read the chunk type and chunk
length from the chunk_hdr member of chunk. But call to
sctp_sf_violation_paramlen() always with 'struct sctp_paramhdr' type's
parameter, it will be passed to sctp_sf_abort_violation(). This may
cause kernel panic."

Upstream commit: ba0166708ef4da7eeb61dd92bbba4d5a749d6561

This is user-triggerable.

Thanks, Eugene
