Arbitrary code execution via IOHIDFamily out-of-bounds write
Published Nov 1, 2022 · Updated Apr 21, 2025
Out-of-bounds write in IOHIDFamily in Apple macOS before 13 allows local users to crash an app or execute arbitrary code via a malicious app. IOHIDFamily mishandles internal state and writes outside an intended buffer, corrupting memory; Apple has not disclosed the exact state transition or buffer. Execution requires a local user to launch the malicious app, and the bounded consequences are application termination or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <13
- Affected versionversion=unspecified <16.1
