Current Description
Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.

Xen 3.3.x hasta la versión 4.5.x y en el kernel de Linux hasta la versión 3.19.1 no restringe adecuadamente el acceso al registro de comandos PCI, lo que podría permitir a usuarios locales del SO invitados provocar una denegación de servicio (interrupción no enmascarable y caída del host) deshabilitando (1) la memoria o (2) la descodificación I/O para un dispositivo PCI Express posteriormente accediendo al dispositivo, lo que desencadena una respuesta Unsupported Request (UR).
