Summary
Vulnerability in Oracle VM VirtualBox (component Core) affecting version 7.2.16. An easily exploitable flaw allows a low-privileged attacker with local logon to gain unauthorized access to critical data and cause a hang or repeatable crash, and attacks may impact additional products (scope change).
Risk Assessment
An attacker with local access can access critical data and cause a full denial of service, with effects potentially extending beyond VirtualBox. The CVSS score of 8.4 indicates high risk.
Recommendation
Update Oracle VM VirtualBox to a patched version immediately. Also restrict local privileges on the host infrastructure to trusted users only.
