Users who created their own config.json objects and didn't prefix a deny-all rule ({"allow": false, "permissions": "rwm"} or equivalent) were not provided protection by the devices cgroup. This would allow malicious containers (with sufficient privileges) to create arbitrary device inodes (assuming they have CAP_MKNOD) and operate on any device inodes they may have access to (assuming they have regular Unix DAC permissions).
