The gas does not push on the vacuum...
It pushes on the body of the rocket as it expands at a faster rate than it can escape from the combustion chamber.

The expelled gas doesn't push on anything in the vacuum of space, except the occasional hydrogen atom, etc. The "push" is on the rocket when the gas is expelled, but after its out, it just expands out into space.

It pushes on the rocket. The gas pushes off from the rocket and that makes the rocket push off from the gas. Just like a bullet fired from a gun pushes off from the gun and the gun kicks back. No third medium is needed. All the action and reaction is between the rocket and its own exhaust, or between the bullet and the gun. I gun fired in a vacuum would still kick back.

itself?
the force of the gas coming from the rocket makes the rocket move (every action has an equal and opposite reaction)

Exhaust gas pushes on the rocket motor. (for every action there is an opposite and equal reaction)

It pushes on the rocket that's expelling it.

The rocket itself. Newton's law - every action has an opposite and equal reaction.
