Description
Kernel core dumps may contain the full contents of system memory at the time of the crash. Kernel core dumps may consume a considerable amount of disk space and may result in denial of service by exhausting the available space on the target file system partition.

ℹ️ Check
Verify that SUSE operating system kernel core dumps are disabled unless needed. Check the status of the "kdump" service with the following command: > systemctl status kdump.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) If the "kdump" service is active, ask the System Administrator if the use of the service is required and documented with the Information System Security Officer (ISSO). If the service is active and is not documented, this is a finding.
