AI-suggested

1. Restrict local access to systems running Windows 11 version 22H2 to trusted users only, employing strict access controls and monitoring. 2. Implement application whitelisting and endpoint detection and response (EDR) solutions to detect unusual privilege escalation attempts. 3. Monitor system logs and kernel event traces for anomalies indicative of exploitation attempts. 4. Use virtualization-based security features and kernel isolation technologies available in Windows 11 to limit kernel attack surface. 5. Once Microsoft releases official patches or updates, prioritize immediate deployment in all affected environments. 6. Employ least privilege principles for user accounts to reduce the impact of potential local exploits. 7. Conduct regular security audits and penetration testing focusing on privilege escalation vectors. 8. Educate users and administrators about the risks of local privilege escalation and the importance of reporting suspicious activity.

Description
