Upgrade SLES:15.0 kernel-macros to version 4.12.14-25.3.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-macros package and not the kernel-macros package as distributed by SLES.
See How to fix? for SLES:15.0 relevant fixed versions and status.
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
