RHEL 10 must be configured so that all local files and directories have a valid group owner.

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

Verify RHEL 10 is configured so that all local files and directories have a valid group with the following command:

$ df --local -P | awk {'if (NR!=1) print $6'} | sudo xargs -I '{}' find '{}' -xdev -nogroup

If any files on the system do not have an assigned group, this is a finding.

Configure RHEL 10 so that all local files and directories have a valid group owner.

Either remove all files and directories from RHEL 10 that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:

$ sudo chgrp <group> <file>
