CVE-2023-42974

Kernel code execution via IOUSBDeviceFamily race

Published Mar 28, 2024 · Updated Nov 4, 2025

A race condition in IOUSBDeviceFamily in Apple iOS, iPadOS, and macOS allows local users to execute code with kernel privileges. IOUSBDeviceFamily mishandles shared state during concurrent operations, creating a race; Apple has not disclosed the specific function or state transition. A malicious app must run locally and win the race; successful exploitation grants kernel-level code execution on the affected device.
