None that wouldn't take decades building forces and population to actually have any hope of retaking it. K8P has taken most of the Karaz Ankor's spare resources and even then it's still barely considered stable by Dwarven standards, and that's thanks to all the humans and halflings. There are some smaller ones, but that's what Thorgrim is doing. All the resources available are being mustered for the Silverspear expedition, which is taking at least a decade to take off.
I'm just guessing, but after Silverspear and Mad Dog Pass are secured, the next goal would likely be Mount Gunbad, because it neighbours Silverspear and therefore an obstacle to trade. After that I can see allocating resources to Karak Kadrin to clear out the Greenskins on the eastern end of Peak Pass. And these are the smaller ones. Taking back something major like Karak Ungor or Karak Drazh would be such an undertaking that I'd imagine it'd take a century to muster enough force to occupy it.
