Qemu emulator built with the USB Net device emulation support is vulnerable to a NULL pointer dereference issue. It could occur while processing remote NDIS control message packets, when the USB configuration descriptor object is null. A privileged user inside guest could use this flaw to crash the Qemu process instance resulting in DoS.
