CVE-2025-24237

System termination via BiometricKit buffer overflow

Published Mar 31, 2025 · Updated Jul 8, 2026

Buffer overflow in BiometricKit across Apple platforms allows local users to cause unexpected system termination through an app. BiometricKit performs insufficient bounds checking when handling app-supplied data, allowing input to exceed the intended buffer; Apple has not disclosed the specific routine or input field. A locally installed app must reach the affected component, and Apple documents only system termination without describing code execution or data access.
