Information
All RHEL 9 local files and directories must have a valid group owner.
GROUP ID: V-257930
RULE ID: SV-257930r991589
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.
Solution
Either remove all files and directories from RHEL 9 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>
