Subject: CVE request: kernel: SCTP memory corruption in HMAC handling


When parsing a peer's supported HMAC authentication options in the
sctp_auth_asoc_get_hmac() function, a malicious peer can craft their
HMAC array in such a way as to cause memory corruption (out-of-bounds
read followed by use of retrieved out-of-bounds data), which at the
very least could cause a denial of service via kernel panic, and
possibly worse.  It appears this could be triggered remotely when
connecting to a malicious peer, or locally by a user acting as both
endpoints.  In both cases, the "auth_enable" sysctl must be set in
order to trigger the bug.
