I have this too - it's some kind of privilege / permissions issue. If you add
'--privileged' to the 'docker run' command it works on my machine:

# docker run -d docker.io/fedora:22 sleep infinity
4972ffef18962f5efea1d01788893434e49816c15168bc8749bca4e4e39c5a1a
# docker exec -it
4972ffef18962f5efea1d01788893434e49816c15168bc8749bca4e4e39c5a1a /bin/bash

goes to host root prompt, but

# docker run -d --privileged docker.io/fedora:22 sleep infinity
a571ab4f15fe1c05f03861e4995f364c2a080854b9aa66312075f3487aa9a798
# docker exec -it
a571ab4f15fe1c05f03861e4995f364c2a080854b9aa66312075f3487aa9a798 /bin/bash

gives me a prompt inside the container:
[root@a571ab4f15fe /]#

This should be fixed by an updated docker-selinux package in docker-1.6.2
