CVE-2022-32947

Kernel code execution via GPU driver memory corruption

Published Nov 1, 2022 · Updated May 6, 2025

Memory corruption in Apple GPU Drivers in macOS before 13 and watchOS before 9.1 allows local users to execute code with kernel privileges. The GPU driver mishandles memory, but Apple has not disclosed the affected routine, input structure, or precise corrupting operation. Exploitation requires a user to run a malicious app, and successful exploitation executes attacker-controlled code in the kernel.
