Kernel code execution via out-of-bounds write
Published Sep 20, 2022 · Updated Oct 21, 2025
Kernel out-of-bounds write in iOS before 15.7 and macOS Big Sur before 11.7 or Monterey before 12.6 allows local users to execute kernel code. The kernel insufficiently bounds-checks an application-controlled value before a memory write; Apple has not identified the affected routine or input. A locally launched app is required, and successful exploitation runs code with kernel privileges across the device.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
