The ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular isochronous transfer descriptor (iTD) list.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
