CVE-2014-3687 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 8.58% chance of exploitation in the next 30 days.
