CVE-2023-32734

Kernel code execution from a local app

Published Jul 27, 2023 · Updated Oct 22, 2024

A kernel memory-handling flaw in affected Apple operating systems allows local users to execute arbitrary code with kernel privileges. The flaw is in the Kernel component, but Apple has not disclosed the faulty operation or the memory-safety condition it corrects. Exploitation requires execution of an attacker-controlled app and yields full kernel-level code execution.
