CVE-2026-64722

Process-memory disclosure via 3D-model buffer overflow

Published Jul 27, 2026 · Updated Jul 27, 2026

Buffer overflow in Apple Model I/O on affected iOS, iPadOS, and macOS releases allows attackers to disclose process memory via a 3D model. Model I/O overflows a buffer while processing untrusted 3D-model data, but Apple has not disclosed the specific parser or copy operation involved. Processing a crafted model requires user interaction and exposes process memory, with no reported integrity or availability impact.
