1.5 UBTU-22-213015

Information

The operating system must disable kernel core dumps so that it can fail to a secure state if system initialization fails, shutdown fails or aborts fail.

GROUP ID: V-260473
RULE ID: SV-260473r1044782

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.

Solution

If kernel core dumps are not required, disable and mask "kdump-tools.service" by using the following command:

$ sudo systemctl mask kdump-tools --now

If kernel core dumps are required, document the need with the ISSO.
