Possible, just like Russel's teapot.

But there has been one very well published Ukrainian attack launched from Russian soil[1].

If Ukraine had could regularly smuggle several drone aircraft's and explosives into Russia and launch them, we would be seeing a lot of other effects. Such as attacks on weapon production sites deep into Russia[2].

But yes, a lot of those attacks are probably unsuccessful. With my qualifications as armchair general, I would be surprised if more than 10% of them was successful.

I also don't think they'll target the Yelabuga drone factory with a drone when they could use that drone on something relatively small but high value (like an aircraft) or combustible (like a refinery), and are waiting for their heavy cruise missles to come online for targets like factories. You can't do much damage to a factory with a drone. We've seen Ukraine target industrial sites with drones, but it's not common.
