Memory corruption via SceneKit out-of-bounds write
Published Sep 14, 2026 · Updated Sep 14, 2026
Out-of-bounds writes in SceneKit in affected Apple operating systems allow attackers to corrupt memory by processing a crafted 3D model. SceneKit writes beyond an allocation while parsing model data, but Apple has not disclosed the exact parser, field, or missing bounds check. Exploitation requires an affected device to process attacker-controlled model content; Apple reports memory corruption without specifying code execution or a crash.

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.
