| Doc Text: |
An infinite-loop issue was found in the QEMU emulator built with USB EHCI emulation support. The flaw occurred during communication between the host controller interface(EHCI) and a respective device driver. These two communicate using an isochronous transfer descriptor list(iTD); an infinite loop unfolded if there was a closed loop in the list. A privileged user inside a guest could use this flaw to consume excessive resources and cause denial of service.
