The k8s exploit requires stars to be aligned for an external attacker: the pod you exploit (via an RCE?) must share some layers with a privileged pod running in the same node. Or alternatively, you should have the ability to run an arbitary image as an unprivileged pod. Which is surely, some environments where internal teams might have such access. But getting there for a remote attacker isn't easy.
