Fix Recommendation

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

$ systemctl mask --now systemd-coredump.socket

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

Reload the daemon for this change to take effect.

$ systemctl daemon-reload

Check Contents

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

$ systemctl status systemd-coredump.socket
systemd-coredump.socket
Loaded: masked (Reason: Unit systemd-coredump.socket is masked.)
Active: inactive (dead) since Mon 2024-02-26 13:31:02 UTC; 26s ago
