How to fix?

Upgrade SLES:15.0 kernel-livepatch-4_12_14-25_16-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_16-default package and not the kernel-livepatch-4_12_14-25_16-default package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks.
