Discussion

A core dump includes a memory image taken at the time the operating system terminates an application. The memory image could contain sensitive data and is generally useful only for developers trying to debug problems.

Note: If kernel dumps are disabled in accordance with RHEL-10-701090, this requirement is not applicable.

Verify RHEL 10 disables core dumps for all users by issuing the following command:

$ sudo grep -r core /etc/security/ | grep -v '#'
/etc/security/limits.d/core_dumps.conf:* hard core 0

This can be set as a global domain (with the * wildcard) but may be set differently for multiple domains.

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