Randstorm is specific to javascript implementations of bitcoin (as in bitcoin-js, not sure if there are others). Bitcoin core is unaffected, it’s written in C++.

Keybleed is just unciphered’s wallet checker app, right? Not some separate vulnerability?

My understanding is that it only effects wallets which used bitcoin-js, so core and most wallets are safe. It should only effect wallets generated in a web browser like paper wallet generators and those at a handful of sites. Bitcoin core and most desktop clients should be safe from this.
