Kernel-state disclosure via IOSurface out-of-bounds read
Published Jun 23, 2023 · Updated Dec 5, 2024
Out-of-bounds read in IOSurface in Apple iOS, iPadOS, and macOS allows local users to leak sensitive kernel state through an app. Apple has not disclosed the IOSurface code path or input field; insufficient input validation permits a read beyond a valid buffer. Execution of an app by a local user is required, and the reported consequence is kernel-state disclosure without integrity or availability 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.
