Hello,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.
