Description Prasad J Pandit 2017-02-13 09:50:54 UTC
Quick emulator(Qemu) built with the USB xHCI controller emulator support is
vulnerable to an infinite loop issue. It could occur while processing control
transfer descriptors' sequence in xhci_kick_epctx.

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS.
