CVE-2014-9065

Estado: ModificadaMedia (4.4)—

common/spinlock.c en Xen 4.4.x y anteriores no maneja correctamente los bloqueos de lectura y escritura, lo que permite a usuarios locales invitados de x86 causar una denegación de servicio (denegación de escritura o fin de sesión de la vigilancia NMI y caída del anfitrión) a través de un número grande de solicitudes de lectura, una vulnerabilidad diferente a CVE-2014-9066.
