Common Development and Distribution License 1.0 is a file-level (or library-level) copyleft license. You can include Common Development and Distribution License 1.0 files in a MIT License project; the Common Development and Distribution License 1.0 files retain their copyleft obligation (changes must be released), while the project at large can stay MIT License. Keep file boundaries clear.
