posted Monday, July 11, 2016 at 12:04 PM EDT
Despite the advisory being only recently released, Canon has already developed a fix for the problem. Firmware v.1.0.2 is now available here, which "incorporates countermeasures for a phenomenon in which the bottom part of still images recorded to SanDisk CFast cards become corrupted." In addition, communication reliability between the camera and CFast cards in general has been improved.
