Vulnerability Discussion
Unowned files and directories may be unintentionally inherited if a user is assigned the same User Identifier "UID" as the UID of the unowned files.
Check
Verify all files and directories on OL 8 have a valid owner with the following command:
$ sudo find / -nouser
If any files on the system do not have an assigned owner, this is a finding.
Fix
Either remove all files and directories from the system that do not have a valid user or assign a valid user to all unowned files and directories on OL 8 with the "chown" command:
$ sudo chown
