A flaw was found in the machine-config-operator that causes an OpenShift node to become unresponsive when a container consumes a large amount of memory. An attacker could use this flaw to deny access to schedule new pods in the OpenShift cluster. This was fixed in openshift/machine-config-operator 4.4.3, openshift/machine-config-operator 4.3.25, openshift/machine-config-operator 4.2.36.
