Check Text (C-242457r961863_chk)
Review the Kubernetes Kubeadm kubelet conf file by using the command:
stat -c %U:%G /var/lib/kubelet/config.yaml| grep -v root:root
If the command returns any non root:root file permissions, this is a finding.
Fix Text (F-45690r712726_fix)
Change the ownership of the kubelet config to "root: root" by executing the command:
chown root:root /var/lib/kubelet/config.yaml
