OL08-00-010670 - OL 8 must disable kernel dumps unless needed.

Information

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.

OL 8 installation media presents the option to enable or disable the kdump service at the time of system installation.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

If kernel core dumps are not required, 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.
