How to fix?

Upgrade Centos:8 runc to version 0:1.0.0-61.rc8.module+el8.1.0+4873+4a24e241 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream runc package and not the runc package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.
