Fix Recommendation

Configure the system to disable the systemd-coredump.socket with the following command:

$ sudo systemctl mask --now systemd-coredump.socket

Created symlink /etc/systemd/system/systemd-coredump.socket -> /dev/null

Reload the daemon for this change to take effect.

$ sudo systemctl daemon-reload

Note: If kernel dumps are disabled in accordance with RHEL-09-213040, this requirement is not applicable.

Verify RHEL 9 is not configured to acquire, save, or process core dumps with the following command:

$ sudo systemctl status systemd-coredump.socket

systemd-coredump.socket
Loaded: masked (Reason: Unit systemd-coredump.socket is masked.)
