Prasad J Pandit, Red Hat Product Security Team, reports:

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.
