Bournemouth boss Eddie Howe is looking to bolster his attacking options in this month's transfer window and has targeted a move for Mason.
Howe is thought to be a big fan of Mason and is thought to have tried to sign him in the summer.
Mason only recently returned to Cardiff earlier this month after a successful spell on loan at Bolton Wanderers.
Bolton have expressed an interest in bringing Mason back to the Reebok Stadium, but Bournemouth are hoping to win the race for the 22-year-old.
Sky Sports understands the Cherries have tabled a £1.5million bid for Mason as they look to lure him away from Cardiff.
