CVE-2023-34425

Kernel code execution via undisclosed memory flaw

Published Jul 28, 2023 · Updated Feb 13, 2025

A memory-handling flaw in Apple Neural Engine on affected iOS, iPadOS, macOS, and watchOS releases allows local users to execute kernel code. Apple has not disclosed the faulty memory operation, affected function, or attacker-controlled input; it states only that improved memory handling addressed the issue. Exploitation requires an app to run locally on a device containing the affected component and grants kernel-level code execution.
