The PCI backend driver in Xen, when running on an x86 system and using
Linux 3.1.x through 4.3.x as the driver domain, allows local guest
administrators to hit BUG conditions and cause a denial of service
(NULL pointer dereference and host OS crash) by leveraging a system
with access to a passed-through MSI or MSI-X capable physical PCI
device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux
pciback missing sanity checks."
