CVE-2026-64766

Code execution via SceneKit integer overflow

Published Jul 27, 2026 · Updated Jul 27, 2026

SceneKit integer overflow in Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows attackers to execute code via a malicious file. SceneKit accepts attacker-controlled file values for an integer calculation without sufficient validation, causing the calculation to overflow; Apple has not disclosed the affected function, file format, or resulting memory operation. Exploitation requires an application or user to process the file and can crash the application or execute code in its process context.
