Vardy swept home at the end of one of many excellent moves the Foxes produced during the course of an entertaining game at the King Power Stadium before Maddison rifled a superb finish into the bottom corner to double the lead 15 minutes from time.
Leicester had earlier been denied by the crossbar as Wilfred Ndidi’s 12-yard shot found a wooden home, while Vardy had been denied in the first half by a vital touch from Callum Chambers sliding back at the far post.
The defeat plunges Unai Emery‘s future into yet more doubt, with Arsenal now eight points off the top four and without a win in five games in all competitions.
Leicester, conversely, leapfrog Chelsea and Manchester City – still to play against Liverpool – and could end the weekend just five points off the Premier League leaders.
