NVD Description

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

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using "--userns-remap", if the root user in the remapped namespace has access to the host filesystem they can modify files under "/var/lib/docker/<remapping>" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user.
