CVE-2022-22587Known exploitation

Kernel-code execution via insufficient framebuffer input validation

Published Mar 18, 2022 · Updated Oct 21, 2025

Memory corruption in Apple IOMobileFrameBuffer allows local users to execute kernel-privileged code on iOS, iPadOS, and macOS. Apple identifies insufficient input validation in the component as the source of memory corruption but does not disclose the exact code path or input. A malicious application must already run locally; successful exploitation crosses into the kernel, and Apple reported active exploitation.
