CVE-2022-42858

Kernel code execution via AMD memory corruption

Published Apr 10, 2023 · Updated Feb 11, 2025

Memory corruption in the AMD component of Apple macOS Ventura before 13.1 allows local users to execute code with kernel privileges. The AMD component insufficiently validates an undisclosed input before processing it, corrupting memory; Apple has not published the affected routine or input format. Exploitation requires a user to run a crafted local app, after which attacker-controlled code can execute in the kernel.
