NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump package and not the kernel-kdump package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
