CVE-2022-42846

System crash via crafted video parsing

Published Dec 15, 2022 · Updated Apr 21, 2025

Memory corruption in the Apple Graphics Driver allows context-dependent attackers to terminate iOS and iPadOS via crafted video. The driver mishandles memory while parsing attacker-controlled video, although Apple has not disclosed the exact invalid memory operation. Exploitation requires the device to parse the file; the documented consequence is a system crash, with no disclosed data access or code execution.
