AI-suggested

Organizations should monitor Microsoft security advisories closely and apply patches promptly once released for Windows 11 Version 24H2. Until patches are available, restrict local user privileges to the minimum necessary to reduce the attack surface. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of privilege escalation attempts. Conduct regular audits of user accounts and permissions to ensure no unnecessary elevated privileges exist. Implement strict network segmentation to limit lateral movement if a local compromise occurs. Additionally, consider deploying virtualization-based security features available in Windows 11 to isolate critical processes. Developers and system architects should review concurrency controls in custom applications to avoid similar race conditions. Finally, maintain comprehensive backups and incident response plans to mitigate potential impacts of exploitation.

Description

Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Brokering File System allows an authorized attacker to elevate privileges locally.
