Description
The "root" group is a highly privileged group. Furthermore, the group-owner of this file should not have any access privileges anyway.
ℹ️ Check
Verify the group ownership of the "/boot/grub2/grub.cfg" file with the following command: $ stat -c "%G %n" /boot/grub2/grub.cfg root /boot/grub2/grub.cfg If "/boot/grub2/grub.cfg" file does not have a group owner of "root", this is a finding.
✔️ Fix
Change the group of the file /boot/grub2/grub.cfg to root by running the following command: $ chgrp root /boot/grub2/grub.cfg
