Le Fondre has been on the books of Cardiff since 2014 and has a contract with the Welsh outfit until June 2017, according to Transfermarkt.co.uk.
The Englishman played on loan for Championship rivals Wolverhampton Wanderers this season.
The striker failed to make a massive impact at the Molineux Stadium, scoring just three goals in 26 Championship appearances for Wolves.
Le Fondre created 16 chances, had a pass accuracy of 72% and a shot accuracy of 57%, and won 22 headers, five dribbles and four tackles.
Wolves finished 14th in the Championship this season, below Leeds and Cardiff City.
