Qemu: usb: xhci memory leakage during device unplug
Memory leak in the usb_xhci_exit function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator), when the xhci uses msix, allows local guest OS administrators to cause a denial of service (memory consumption and possibly QEMU process crash) by repeatedly unplugging a USB device.
A memory-leak flaw was found in the Quick Emulator(QEMU) built with USB xHCI controller emulation support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly resulted in leaking host memory, which affected other services on the host. A privileged user inside the guest could exploit this flaw to cause a denial of service on the host or potentially crash the host's QEMU process instance.

CVE-2016-7466 Qemu: usb: xhci memory leakage during device unplug
Quick Emulator(Qemu) built with the USB xHCI controller emulation support is
vulnerable to a memory leakage issue. It could occur while doing a USB device
unplug operation; Doing so repeatedly would result in leaking host memory,
affecting other services on the host.
A privileged user inside guest could use this flaw to cause a DoS on the host
and/or potentially crash the Qemu process instance on the host.
