How to fix?

Upgrade RHEL:7 kernel-debug to version 0:3.10.0-327.el7 or higher.
This issue was patched in RHSA-2015:2152.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished.
