This advisory relates to Red Hat OpenShift Container Platform 4.12.97 and includes updates primarily for container images. No direct security fixes are included in this release for OpenShift itself. However, a related Red Hat Enterprise Linux 9 update addresses a moderate severity security vulnerability (CVE-2025-11234) in the qemu-kvm package, specifically a use-after-free issue in the VNC WebSocket handshake. Users of affected Red Hat Enterprise Linux 9 versions should apply the qemu-kvm update to mitigate this vulnerability. The OpenShift advisory recommends upgrading to the updated packages and images when available but does not list new security fixes for OpenShift 4.12.97 itself.
