NVD Description
Note: Versions mentioned in the description apply only to the upstream snapd package and not the snapd package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
When generating the systemd service units for the docker snap (and other similar snaps), snapd does not specify Delegate=yes - as a result systemd will move processes from the containers created and managed by these snaps into the cgroup of the main daemon within the snap itself when reloading system units. This may grant additional privileges to a container within the snap that were not originally intended.
