CVE-2022-42850

Kernel code execution via Graphics Driver memory corruption

Published Dec 15, 2022 · Updated Apr 21, 2025

Memory corruption in the Graphics Driver in Apple iOS and iPadOS before 16.2 allows local users to execute code with kernel privileges. The driver mishandles memory while processing app-controlled data, but Apple has not disclosed the exact object, operation, or memory-safety failure. Execution requires a user to run a crafted app, after which attacker-controlled code operates in the kernel and can compromise the device.
