kernel.kexec_load_disabled = 1

Load settings from all system configuration files with the following command:

$ sysctl –system

Check Contents

Verify AlmaLinux OS 9 is configured to disable kernel image loading.

Check the status of the kernel.kexec_load_disabled kernel parameter with the following command:

$ sysctl kernel.kexec_load_disabled

kernel.kexec_load_disabled = 1

If "kernel.kexec_load_disabled" is not set to "1" or is missing, this is a finding.

Check that the configuration files are present to enable this kernel parameter with the following command:

$ /usr/lib/systemd/systemd-sysctl --cat-config | grep kernel.kexec_load_disabled

kernel.kexec_load_disabled = 1

If "kernel.kexec_load_disabled" is not set to "1" or is missing, this is a finding.
