CVE-2026-7374
Detail
Awaiting Enrichment This CVE record has been marked for NVD enrichment efforts.
Description
A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.

Title: Kubevirt en Red Hat, Description: Se encontró una falla en el componente virt-handler de KubeVirt. Esta vulnerabilidad permite a un usuario autenticado de OpenShift con permisos de edición en un único espacio de nombres explotar una validación incorrecta de enlaces simbólicos al conectarse a los sockets de consola de la máquina virtual. Al reemplazar el socket de la consola con un enlace simbólico al socket del tiempo de ejecución de contenedores (CRI-O) del host, un atacante puede secuestrar la conexión privilegiada del virt-handler. Esto permite al atacante acceder a cualquier socket Unix en el host, lo que podría llevar al control total del nodo y de todo el clúster.

Description
A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.
