I've been using wood putty to repair all the cracks on my cobs for years. Some were superficial, and some you could fit a nickle through it. If you have any available, just pack some in the hole, wait a day and smoke.
And don't listen to those who say "just buy a new one". I get it, I'll keep repairing my legend untill it no longer holds any tobacco in it.
