How to fix?

Upgrade SLES:15.1 docker-runc to version 1.0.0rc8+gitr3917_3e425f80a8c9-6.32.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream docker-runc package and not the docker-runc package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.)
