An infinite loop flaw was found in the USB OHCI controller emulator of QEMU. This flaw occurs while servicing OHCI isochronous transfer descriptors (TD) in the ohci_service_iso_td routine, as it retires a TD if it has passed its time frame. It does not check if the TD was already processed and holds an error code in TD_CC. This issue may happen if the TD list has a loop. This flaw allows a guest user or process to consume CPU cycles on the host, resulting in a denial of service.
