Descriptions

Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors.

Xen con versiones enteriores a 4.1.x, 4.2.x, 4.3.x, y no toma la page_alloc_lock grant_table.lock en el mismo orden, lo que permite a los administradores invitados locales con acceso a múltiples vcpus causar una denegación de servicio (bloqueo host) a través sin especificar vectores.
