CVE-2022-42828

Kernel code execution by local applications

Published Aug 14, 2023 · Updated Oct 9, 2024

Memory handling in the VPN component of Apple macOS before 13 allows local users to execute arbitrary code with kernel privileges. Apple identifies only improved memory handling as the correction and has not disclosed the faulty operation or the input that reaches it. Execution requires a locally running app, and successful exploitation crosses into kernel privilege, allowing complete control within the operating system.
