CVE-2026-13622

Node compromise via symlinked migration socket

Published Aug 12, 2026 · Updated Aug 16, 2026

Symlink following in virt-handler in Red Hat OpenShift Virtualization allows remote authenticated users to compromise a node via live migration. The target-side migration proxy opens Unix sockets under /proc//root/ with net.Dial() and does not prevent symlink resolution, so a writable socket path in the virt-launcher pod can be redirected to the host CRI-O socket. Exploitation requires namespace edit and pods/exec permissions during a VM live migration; successful abuse turns the root-run host-side proxy into a bidirectional relay to the container runtime, enabling container escape and full node compromise.
