Process-memory disclosure via crafted image processing
Published Feb 11, 2026 · Updated Feb 11, 2026
Information disclosure in Apple ImageIO allows attackers to read process memory when an affected device processes a crafted image. ImageIO mishandles memory while decoding attacker-controlled image data, but Apple has not disclosed the exact operation or memory-safety defect. Exploitation requires a user or application to process the image; the disclosed consequence is confined to process-memory exposure.

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 <18.7
- Affected versionversion=unspecified <26.3
