RHEL-10-700810 - RHEL 10 must prevent a user from overriding the disable-restart-buttons setting for the graphical user interface.
Information
A user who is at the console can reboot the system at the login screen. If restart or shutdown buttons are pressed at the login screen, this can create the risk of short-term loss of availability of systems due to reboot.Solution
Configure RHEL 10 to prevent a user from overriding the disable-restart-buttons setting for graphical user interfaces.Note: The example below is using the database "local" for the system. If the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory.
Update the "/etc/dconf/db/local.d/locks/session" file to prevent nonprivileged users from modifying the disable-restart-buttons setting:
$ sudo vi /etc/dconf/db/local.d/locks/session
/org/gnome/login-screen/disable-restart-buttons
Run the following command to update the database:
$ sudo dconf update
