From https://bugzilla.redhat.com/show_bug.cgi?id=1414108:

Quick Emulator(Qemu) built with the ac97 audio device emulation support is
vulnerable to a memory leakage issue. It could occur while doing a device
unplug operation; Doing so repeatedly would result in leaking host memory,
affecting other services on the host.

A privileged user inside guest could use this flaw to cause a DoS and/or
potentially crash the Qemu process on the host.

Upstream patch:
---------------
  -> https://lists.nongnu.org/archive/html/qemu-devel/2017-01/msg01740.html
