How to fix?

Upgrade SLES:15.0 kernel-vanilla-base to version 4.12.14-150.22.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-vanilla-base package and not the kernel-vanilla-base package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.
