CVE-2024-54529Public exploit

Elevated code execution via audio object type confusion

Published Dec 11, 2024 · Updated Apr 2, 2026

Type confusion in Apple macOS 13 before 13.7.2, 14 before 14.7.2, and 15 before 15.2 allows local users to execute elevated code. CoreAudio audiohald Mach handlers fetch a HALS_Object using an attacker-controlled identifier, assume it is an ioct object without validating its type, and make a virtual call through the mismatched object. Execution requires a local app to run; successful exploitation escapes its sandbox or gains the privileges of the coreaudiod service.
