Process-memory disclosure via crafted image processing
Published May 8, 2023 · Updated Jan 29, 2025
Image-processing flaw in Apple macOS Big Sur before 11.7.5 and Ventura before 13.3 allows attackers to disclose process memory. Carbon Core performs insufficient checks while processing maliciously crafted image data, but Apple has not disclosed the specific check, parser path, or memory operation involved. Exploitation requires local image processing 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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <11.7
