Process-memory disclosure via malicious image processing
Published Jul 29, 2025 · Updated Apr 2, 2026
Information disclosure in Model I/O in Apple macOS before 15.6 allows local users to read process memory via a crafted image. Apple has not disclosed the exact image parser or failed check; the advisory states only that improved checks addressed the issue. Exploitation requires user interaction to process the image, and the reported consequence is limited to disclosure of memory from the affected process.
