Description Robert Frohl 2023-02-21 13:24:58 UTC 
CVE-2023-0664

A privilege escalation vulnerability was found in the QEMU Guest Agent service for Windows. A local unprivileged user is able to manipulate the QEMU Guest Agent's Windows installer (via repair custom actions) to elevate their privileges to the SYSTEM account within the guest.

Note: this is not a VM escape flaw, meaning that it does *not* allow a malicious user to break out of the guest. It affects Windows VMs using virtio-win drivers with QEMU Guest Agent installed in the guest.
