CVE-2026-62940

Incus is a system container and virtual machine manager. Prior to version 7.3.0, when migrating an instance to another cluster member, user-supplied configuration overrides (including security-critical keys like `security.privileged` and `raw.lxc`) are applied without any project restriction enforcement, allowing a restricted project user to escalate to a privileged container and escape to the host. Version 7.3.0 patches the issue.

Summary		(es) Incus es un gestor de contenedores de sistema y máquinas virtuales. Antes de la versión 7.3.0, al migrar una instancia a otro miembro del clúster, las anulaciones de configuración proporcionadas por el usuario (incluidas claves críticas de seguridad como 'security.privileged' y 'raw.lxc') se aplican sin ninguna aplicación de restricciones de proyecto, permitiendo a un usuario de proyecto restringido escalar a un contenedor privilegiado y escapar al anfitrión. La versión 7.3.0 corrige el problema.
