CVE-2022-42832

Kernel code execution via PPP race condition

Published Nov 1, 2022 · Updated Apr 21, 2025

Race condition in PPP in Apple macOS before 13 allows attackers controlling a root-privileged app to execute code with kernel privileges. The PPP component fails to lock a shared resource correctly during concurrent access; Apple has not disclosed the affected function or resource. Exploitation is local, requires existing root privileges, and crosses the remaining boundary into kernel code execution.
