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.”
