Kernel-memory disclosure via out-of-bounds read
Published May 8, 2023 · Updated Jan 29, 2025
Out-of-bounds read in the Apple kernel in iOS, iPadOS, and macOS allows local users to disclose kernel memory through an app. The kernel reads beyond a validated input boundary, returning adjacent kernel memory to the calling app rather than rejecting the request. Execution of an attacker-supplied app and user interaction are required; the documented consequence is disclosure, not modification or service interruption.

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.
