China and/or Russia might have a collection of zero-days they've been sitting on, which they could surreptitiously provide to Iran. Of course, there's attribution risk there, and the opportunity cost of not saving those zero-days for their own later use.

It seems kind of unlikey to me. Cyber attacks are unlikely to meaningfully change the result of the war, so it would kind of just be a waste from the china/russia perspective. They so far havent lifted a finger to do anything for iran that wasn't free for them, so i doubt they would waste exploits on this.
