This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
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).
