CVE-2022-42803

Kernel code execution via undisclosed race condition

Published Nov 1, 2022 · Updated Apr 22, 2025

Kernel race condition in Apple macOS, tvOS, and watchOS allows local users to execute arbitrary code with kernel privileges. Apple identifies the locus only as the kernel and has not disclosed the competing operations, shared object, or affected routine behind the improper locking. An attacker-controlled local app and race timing are required; successful exploitation crosses the user-to-kernel boundary on macOS before 13, tvOS before 16.1, and watchOS before 9.1.
