: hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface.

Comment
: QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.
