Kernel-memory disclosure via IOSurfaceAccelerator out-of-bounds read
Published Jun 23, 2023 · Updated Dec 5, 2024
An IOSurfaceAccelerator out-of-bounds read in Apple iOS, iPadOS, tvOS, and watchOS allows local users to disclose kernel memory. IOSurfaceAccelerator fails to reject app-supplied input before an out-of-bounds kernel-memory read; Apple has not disclosed the specific routine or input field. Exploitation requires a user to run an app on an affected device, and the reported consequence is kernel-memory disclosure only.

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.
