CVE-2022-42830

Kernel code execution via ppp out-of-bounds write

Published Nov 1, 2022 · Updated Apr 21, 2025

Memory corruption in the ppp component of Apple macOS before 13 allows local users with root privileges to execute kernel code. The component performs an out-of-bounds write during memory handling, but Apple has not disclosed the affected function or input. Exploitation requires an already root-privileged app and permits arbitrary instructions to run in the kernel, beyond normal user-space controls.
