This is a local privilege escalation vulnerability in the Core component of Oracle VM VirtualBox 7.2.16. The vulnerability requires high privileges and local logon access to the host system where VirtualBox is running, with no user interaction needed. A successful exploit can cause a partial denial of service (partial DOS) affecting the availability of VirtualBox.
