hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
