CVE-2014-4667
The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet.
Does this matter?
Lower severity and a low EPSS score (5.93%). Track it; it rarely justifies an emergency change on its own.
