[LoTR] What happened to the rings of the dwarfs?

were they lost long ago?  are they hidden?  did sauron possess them, and if so are they in the rubble of barad-dur?

Dwarvish hardiness prevented them from succumbing to Saurons influence as was his will.  However their greed for gold and jewels was inflamed by possessing the rings and ultimately lead to their downfall.  Thráin II for instance quarried a great horde of treasure in the caverns of Erebor, the lonely mountain which ultimately brought the attentions of Smaug.  His ring, along with two others was reacquired by Sauron for purposes unknown.  According to Gandalf the other were destroyed by the dragons.
