It's a small sonic boom.

The "popping" of the knuckles results from forcing joint fluid to
very rapidly pass from one side of the joint to the other, where the
"sides" are partitioned off by the main bones of the joint. Let me
rephrase that: a joint is an area where two or more separate and distinct
bones meet. The joint fluid provides a cushioning between the joints
so that they don't grate into each other. Cracking your knuckles forces
the joint fluid from one part of the joint to another, and the popping
sound is just the result of the high pressured rushing of fluid.
