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.
Verify kernel core dumps are disabled with the following command: $ systemctl is-active kdump.service inactive If the "kdump" service is active, ask the system administrator (SA) if the use of the service is required and documented with the information system security officer (ISSO). If the service is active, this is a finding.
Disable the "kdump" service with the following command: $ sudo systemctl disable kdump.service If kernel core dumps are required, document the need with the ISSO.
