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.
