CVE-2023-32368

Process-memory disclosure via malformed 3D model

Published Jun 23, 2023 · Updated Dec 5, 2024

An out-of-bounds read in Apple Model I/O across affected platforms allows attackers to disclose process memory via a crafted 3D model. Model I/O reads beyond an input buffer while parsing insufficiently validated model data, exposing bytes from the hosting process. Reachability requires local processing of attacker-controlled model content and user interaction; no integrity or availability impact is reported.
