CVE-2022-32911

Kernel code execution via out-of-bounds write

Published Sep 20, 2022 · Updated May 29, 2025

Kernel memory corruption in Apple iOS before 16 and macOS before 11.7 or 12.6 allows local users to execute code with kernel privileges. The Kernel component performs an out-of-bounds write while handling app-controlled data, but Apple has not disclosed the affected routine or data structure. A locally running app with low privileges can cross the kernel boundary and gain complete control of the device.
