Bennett, who has been on the books of Villa since 2012, played on loan for Wednesday during the second half of the 2015-16 season.
The 26-year-old left-back joined the Owls on loan from the Villans in the January transfer window, but he could not play a massive role in Wednesday’s match to the Championship playoff final due to injury.
In three Championship appearances for the Owls, the former England Under-21 international defender created three chances, had a pass accuracy of 83%, and won two headers, two dribbles and eight tackles.
The Owls lost 1-0 to Hull City at the Wembley Stadium in London on Saturday evening, thanks to a stunning strike from Mohamed Diame in the 72nd minute.
