How to fix?

Upgrade SLES:15.0 kernel-livepatch-4_12_14-25_3-default to version 1-1.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-4_12_14-25_3-default package and not the kernel-livepatch-4_12_14-25_3-default package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

In the Linux Kernel before version 4.15.8, 4.14.25, 4.9.87, 4.4.121, 4.1.51, and 3.2.102, an error in the "_sctp_make_chunk()" function (net/sctp/sm_make_chunk.c) when handling SCTP packets length can be exploited to cause a kernel crash.
