How to fix?

Upgrade SLES:15.0 kernel-vanilla-base to version 4.12.14-25.3.1 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.

In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in JFS can be triggered by calling setxattr twice with two different extended attribute names on the same file. This vulnerability can be triggered by an unprivileged user with the ability to create files and execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.
