The OpenShift Container Platform 4.12 release fixes an issue with entering a debug session on a target node when the target namespace lacks the appropriate security level. This caused the oc CLI to prompt you with a pod security error message. If the existing namespace does not contain the appropriate security levels, OpenShift Container Platform now creates a temporary namespace when you enter oc debug mode on a target node. (OCPBUGS-852)
