Kernel code execution via out-of-bounds write
Published Nov 1, 2022 · Updated Oct 21, 2025
Out-of-bounds write in the iOS and iPadOS kernel allows local users to execute code with kernel privileges through a malicious application. Apple has not disclosed the affected kernel operation; insufficient bounds checking permits an application-triggered write beyond an intended memory boundary. Execution requires a local application and user interaction, and successful exploitation grants kernel privileges with full device impact.

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.
- Affected versionversion=unspecified <15.7
