Fix Recommendation

Configure the operating system to disable core dump backtraces.

Add or modify the following line in /etc/systemd/coredump.conf:

ProcessSizeMax=0

Check Contents

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

Verify RHEL 9 disables core dump backtraces by issuing the following command:

$ grep -i ProcessSizeMax /etc/systemd/coredump.conf

ProcessSizeMax=0

If the "ProcessSizeMax" item is missing or commented out, or the value is anything other than "0", and the need for core dumps is not documented with the information system security officer (ISSO) as an operational requirement for all domains that have the "core" item assigned, this is a finding.
