Title

RHEL 9 must disable acquiring, saving, and processing core dumps.

Control

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.) Active: inactive (dead) If the "systemd-coredump.socket" is loaded and not masked, and the need for core dumps is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.

Discussion

A core dump includes a memory image taken at the time the operating system terminates an application. The memory image could contain sensitive data and is generally useful only for developers trying to debug problems.

Fix

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
