A successful exploit needs necessary privileges (CAP_NET_ADMIN) and direct, local access. A local user in RHCOS is already a root with full permissions, hence existence of this vulnerability does not bring any value from the potential attacker perspective. From the OpenShift containers perspective, this vulnerability cannot be exploited as in OpenShift the cluster processes on the node are namespaced, which means that switching the namespace in the running OpenShift container will not bring necessary capabilities.\nThis means that for OpenShift, the impact of this vulnerability is Low.\nSimilar to the CVE-2023-32233 vulnerability, this has been explained in the following blog post as an example of a \"Container escape vulnerability\":\nhttps://www.redhat.com/en/blog/containers-vulnerability-risk-assessment", "threat_severity": "Important"}
