CVE-2023-41995

Kernel code execution via use-after-free

Published Sep 26, 2023 · Updated Nov 4, 2025

Use-after-free in the Apple kernel before iOS and iPadOS 17 or macOS 14 allows local users to execute code with kernel privileges. Kernel code accesses an object after its memory has been freed, but Apple has not published the affected routine or object type. Execution requires an attacker-controlled app to run, after which kernel-level code can compromise the operating system.
