An exploitable vulnerability in the DCCP (Datagram Congestion Control Protocol) networking code was found, which
allows a local user to execute arbitrary code within ring 0 and elevate privileges to root.

SUSE Linux Enterprise Server 12 SP 1 and 2:

DCCP protocol is not built into the kernel versions at all thus no SLES12 versions are affected.

SUSE Linux Enterprise Server 11 SP 1 to 4:

DCCP protocol is built but not supported and not installed by default. It is only available via the EXTRAS repository.
