Summary
An untrusted pointer dereference in Windows Virtualization-Based Security (VBS) Enclave allows an authorized attacker to bypass a security feature locally.
Risk Assessment
An attacker with local access and valid credentials can bypass the VBS security feature, potentially leading to isolation breach and further escalation. Authentication is required.
Recommendation
Apply Microsoft Windows security updates. Restrict local system access to trusted users.
