The 29-year-old former Chelsea defender goes straight into their squad for the game against Reading at the Britannia Stadium.
Stoke boss Tony Pulis moved to plug the gap in his defence with both Gerry Taggart and skipper Clive Clarke suspended for the visit of Steve Coppell's side.
The Potters director of football John Rudge is pleased with the acquisition of Duberry, who came close to a move to Wolves in the summer and has not featured for Leeds since the end of August.
He said: "We're delighted to get him. He's an experienced defender who has played at the highest level with Leeds and Chelsea and he will add quality and competition to our squad. There is no doubt his arrival gives us a boost."
