CVE-2022-32907Public exploit

Kernel code execution via unchecked IOSurface zeroing

Published Nov 1, 2022 · Updated May 6, 2025

Memory corruption in AppleAVD in Apple iOS before 16 and watchOS before 9 allows local users to execute code with kernel privileges. AppleAVDUserClient::decodeFrameFig calculates a pointer into a decoder IOSurface input buffer and calls bzero without ensuring the user-controlled allocation is large enough. Execution of a malicious local app is required; an out-of-bounds zeroing operation permits arbitrary kernel-code execution on the device.
