CVE-2025-64436

KubeVirt is a virtual machine management add-on for Kubernetes. In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.

Summary		(es) KubeVirt es un complemento de gestión de máquinas virtuales para Kubernetes. En 1.5.0 y versiones anteriores, los permisos otorgados a la cuenta de servicio virt-handler, como la capacidad de actualizar VMI y parchear nodos, podrían ser explotados para forzar una migración de VMI a un nodo controlado por un atacante. Esta vulnerabilidad podría, de otro modo, permitir a un atacante marcar todos los nodos como no programables, forzando potencialmente la migración o creación de pods privilegiados en un nodo comprometido.
