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.
