Memory leak in QEMU, when built with a VMWARE VMXNET3 paravirtual NIC emulator support, allows local guest users to cause a denial of service (host memory consumption) by trying to activate the vmxnet3 device repeatedly.
A memory-leak flaw was found in the QEMU emulator built with VMWARE VMXNET3 paravirtual NIC emulator support. The flaw occurred when a guest repeatedly tried to activate the VMXNET3 device. A privileged guest attacker could use this flaw to leak host memory, resulting in denial of service on the host.

CVE-2015-8567 CVE-2015-8568 Qemu: net: vmxnet3: host memory leakage
Qemu emulator built with a VMWARE VMXNET3 paravirtual NIC emulator support is
vulnerable to a memory leakage flaw. It occurs when a guest repeatedly tries
to activate the vmxnet3 device.
A privileged guest user could use this flaw to leak host memory, resulting
in DoS on the host.
