Affected: Red Hat RHEL-8-CNV-4.12, Red Hat RHEL-9-CNV-4.14, Red Hat RHEL-9-CNV-4.17, Red Hat RHEL-9-CNV-4.18, Red Hat RHEL-9-CNV-4.19, Red Hat OpenShift Virtualization 4

A container privilege escalation flaw was found in certain Container-native Virtualization images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.
