The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations
emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly
reset certain state information between emulation cycles, which allows
local guest OS users to cause a denial of service (guest OS crash) via
unspecified operations on MMIO regions.
