CVE-2025-43185

Protected user-data access via Voice Control downgrade

Published Jul 29, 2025 · Updated Apr 2, 2026

A downgrade flaw in Voice Control in Apple macOS before 15.6 allows local users to access protected user data through an app. Voice Control accepts downgraded code without sufficient code-signing restrictions, allowing the app to bypass protections applied to current code. Exploitation requires local app execution and user interaction; the documented consequence is disclosure of protected user data, not modification or service interruption.
