Process-memory disclosure via unchecked 3D model read
Published Jul 27, 2023 · Updated Oct 22, 2024
Information disclosure in Apple macOS 12 before 12.6.8 and macOS 13 before 13.5 allows local users to read process memory via a 3D model. Model I/O performs an out-of-bounds read because it does not adequately validate 3D model data before processing it, exposing adjacent process memory. Exploitation requires local access and user interaction to submit and process a crafted model; the documented consequence is memory disclosure only.

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=unspecified <12.6
- Affected versionversion=unspecified <13.5
