+ <p>Certain PV guest kernel operations (page table writes in
+ particular) need emulation, and use Xen's general x86 instruction
+ emulator. This allows a malicious guest kernel which asynchronously
+ modifies its instruction stream to effect the clearing of EFLAGS.IF
+ from the state used to return to guest context.</p>
+ <p>A malicious guest kernel administrator can cause a host hang or
+ crash, resulting in a Denial of Service.</p>
