CVE-2025-43482

Local service interruption via invalid Audio input

Published Dec 12, 2025 · Updated Dec 12, 2025

Improper input validation in macOS Audio before 14.8.3, 15.7.3, and 26.2 allows local users to cause a service interruption. The Audio component insufficiently validates app-supplied input, but Apple has not disclosed the accepted input path or resulting failure mode. A locally running low-privilege app can trigger the availability-only impact without user interaction; no data access or modification is reported.
