System crash via IOHIDFamily out-of-bounds write
Published Sep 15, 2025 · Updated Sep 15, 2025
An out-of-bounds write in IOHIDFamily in affected Apple operating systems allows local users to cause unexpected system termination via an app. IOHIDFamily performs an out-of-bounds write because its bounds checking fails to reject an undisclosed app-controlled input; Apple has not published the affected function or input format. Execution of an app by the local user is required, and the documented consequence is a system crash rather than data access or code execution.

Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <18.7
- Affected versionversion=unspecified <26
