The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack.

Mitigation

SELinux prevents a bind of the SCTP socket by a non-root user.

To mitigate this issue if not using SELinux, or if a Security Context Constraint allows running pods as the root user the 'sctp' module should be blacklisted. Please this this Knowledge Base article for more information on how to blacklist a kernel module. <https://access.redhat.com/solutions/41278&gt;
