Description Prasad Pandit 2017-06-05 11:29:57 UTC

Quick emulator(Qemu) built with the USB xHCI controller emulator support is
vulnerable to an infinite recursive call 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.
