Discussion

Files without a valid group owner may be unintentionally inherited if a group is assigned the same GID as the GID of the files without a valid group-owner.

Check Content

Search the system for files without a valid group-owner.
# find / -nogroup 
If any files are found, this is a finding.

Fix Text

Change the group-owner for each file without a valid group-owner.
# chgrp a validgroup /tmp/a-file-without-a-valid-group-owner
