Description

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.

ℹ️ Check

Verify RHEL 10 interactive users have a valid GID. Check that the interactive users have a valid GID with the following command: $ sudo pwck -r If pwck reports "no group" for any interactive user, this is a finding.

✔️ Fix

Configure RHEL 10 so that all GIDs referenced in "/etc/passwd" are defined in "/etc/group". Edit the file "/etc/passwd" and ensure that every user's GID is a valid GID.
