Out-of-bounds read via SceneKit bounds-check failure
Published Sep 14, 2026 · Updated Sep 14, 2026
An out-of-bounds read in SceneKit in Apple macOS before 15.8, 26.7, or 27 allows attackers to trigger invalid memory reads via 3D files. SceneKit processes crafted 3D data with insufficient bounds checking and reads beyond the intended buffer. Exploitation requires the target to process the file; Apple reports an out-of-bounds read but no code execution, crash, or data-disclosure consequence.

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.
- Affected versionversion=0 <15.8
- Affected versionversion=0 <26.7
- Affected versionversion=0 <27
