Description Kristian Fiskerstrand (RETIRED) gentoo-dev 2015-12-15 14:05:46 UTC
From ${URL}:

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.

Upstream patch:

This issue was discovered by Qinghao Tang of QIHU 360 Marvel Team.

Thank you.
