CVE-2019-7308 (opens in a new tab)How to fix?
Upgrade SLES:15.0 kernel-obs-build to version 4.12.14-150.14.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-obs-build package and not the kernel-obs-build package as distributed by SLES.
See How to fix? for SLES:15.0 relevant fixed versions and status.
kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks.
