CVE-2022-22672

Kernel code execution via MobileAccessoryUpdater memory corruption

Published May 26, 2022 · Updated Aug 3, 2024

Memory corruption in MobileAccessoryUpdater in iOS, iPadOS, and macOS before their fixed releases allows local users to execute arbitrary code with kernel privileges. Apple identifies the affected component and says improved memory handling resolves the issue, but the precise faulty operation on untrusted input is undisclosed. Exploitation requires a malicious application running on the device; successful exploitation gives kernel-level code execution.
