Process-memory disclosure via ImageIO out-of-bounds read
Published Jan 10, 2024 · Updated Jun 20, 2025
Out-of-bounds read in Apple ImageIO allows attackers to disclose process memory when an affected device processes an image. ImageIO reads beyond an image buffer because it does not adequately validate the input before accessing memory outside the buffer's bounds. Exploitation requires a crafted image to reach ImageIO and user interaction; the reported consequence is process-memory disclosure without integrity or availability impact.

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.
