CVE-2014-3687
The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel
through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that
trigger an incorrect uncork within the side-effect interpreter.");
