** Description changed:

- [Non-maskable interrupts triggerable by guests]
+ 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 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.
