** Description changed:

- Linux pciback missing sanity checks leading to crash
+ 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 generate a continuous stream of WARN messages and
+ cause a denial of service (disk consumption) by leveraging a system with
+ access to a passed-through MSI or MSI-X capable physical PCI device and
+ XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity
+ checks."
