CVE-2022-42829

Kernel code execution via ppp use-after-free

Published Nov 1, 2022 · Updated Apr 21, 2025

Use-after-free in Apple macOS before 13 allows local users with root access to execute arbitrary code in the kernel through the ppp component. The ppp component accesses an object after its memory has been freed; Apple has not disclosed the affected function or trigger sequence. A malicious app must already run with root privileges, and successful exploitation crosses into kernel privileges with arbitrary code execution.
