Descriptions
The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion.
La función p2m_teardown en arch/arm/p2m.c en Xen 4.4.x hasta la versión 4.6.x permite a usuarios locales invitados del SO con acceso al dominio del controlador provocar una denegación de servicio (referencia a puntero NULL y caída del SO anfitrión) creando dominios concurrentes y manejando referencias a ellos, relacionado con el agotamiento de VMID.
