Discussion

If a user is assigned the Group Identifier (GID) of a group that does not exist on the system, and a group with the GID is subsequently created, the user may have unintended rights to any files associated with the group.

Check Content

Verify that all AlmaLinux OS 9 interactive users have a valid GID with the following command:
 
$ pwck -r /etc/passwd
 
If the system has any interactive users with a nonexistent primary group, this is a finding.

Fix Text

Configure the system so that all GIDs referenced in "/etc/passwd" are defined in "/etc/group".
