Kernel-memory disclosure via out-of-bounds Neural Engine read
Published Sep 26, 2023 · Updated Nov 4, 2025
Out-of-bounds read in Apple Neural Engine in affected Apple operating systems allows local users to disclose kernel memory through an app. Apple has not disclosed the affected routine or input format; Apple Neural Engine reads past an input boundary because validation is insufficient. Execution of an app and user interaction are required, and the documented impact is limited to kernel-memory disclosure.

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.
