Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.

CVE-2016-6888 Qemu: net: vmxnet: integer overflow in packet initialisation
Quick Emulator(Qemu) built with the VMWARE VMXNET3 NIC device support, with
network abstraction layer is vulnerable to an integer overflow issue. It could
occur while initialisation of a new packets in the device.
A privileged user inside guest could use this flaw to crash the Qemu instance
resulting in DoS.
