Local privilege escalation via TOCTOU race
Published Apr 10, 2025 · Updated Apr 10, 2025
TOCTOU race condition in MSI Center before 2.0.52.0 allows local users to escalate privileges on affected Windows systems. MSI has not disclosed the affected component, the resource checked and later used, or the attacker-controlled replacement that wins the race. Exploitation requires local execution and precise race timing, and success crosses the application's privilege boundary with high confidentiality, integrity, and availability impact.
