CVE-2023-32378

Kernel code execution via IOAcceleratorFamily use-after-free

Published Jan 10, 2024 · Updated Apr 17, 2025

Use-after-free in Apple macOS IOAcceleratorFamily allows local users to execute arbitrary code with kernel privileges through a malicious app. IOAcceleratorFamily accesses an object after its memory has been freed; Apple has not disclosed the specific object or call path. Execution requires a local app to trigger the flaw and yields kernel-level control over the affected Mac.
