Memory corruption via 3D model integer overflow
Published Sep 14, 2026 · Updated Sep 14, 2026
Integer overflow in Apple iOS and iPadOS before 26.7 or 27 allows attackers to corrupt memory by processing a malicious 3D model. The same undisclosed parser flaw affects macOS before 15.8, 26.7, or 27 and tvOS, visionOS, and watchOS before 27; Apple has not identified the overflowing calculation. Exploitation requires an affected device to process attacker-controlled model data, and the public record establishes neither code execution nor data disclosure.

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 <26.7
- Affected versionversion=0 <27
