Warner was the one Australian to fall in an hour-long period before tea on day three, with Australia 1-23 and leading by 196 after bowling India out for 296 earlier on Friday.
With Mohammed Siraj coming over the wicket at him, Warner went at a ball outside off stump but only succeeded in edging it through to wicketkeeper KS Bharat.
Warner scored a fighting 43 in the first innings at The Oval, but would have wanted more runs in the second innings ahead of next week’s first Ashes Test against England.
England’s quicks wreaked havoc against the left-hander on his last Test tour of the country in 2019, keeping him to 95 runs at an average of 9.5.
Warner is all but assured of starting the first Test at Edgbaston, but needs runs to keep his spot and dream of a Sydney farewell to Test cricket next January alive.
His dismissal came after Australia had recovered from a sloppy morning in the field to have India all out after lunch.
Warner, Usman Khawaja and Cameron Green all dropped catches of varying difficulty, while Pat Cummins was denied an lbw through a no-ball for the second time in the match.
Green’s chance was the easiest, putting down what should have been a regulation catch in the gully off Cummins when Shardul Thakur had eight.
But he made up for it after the break, taking a screamer to remove Ajinkya Rahane on 89 off Cummins when he flung his right arm out to snare a ball that had appeared to be past him.
Rahane had lived a charmed life until that point, surviving an lbw from a Cummins no-ball on 17 on Thursday and benefiting from Warner’s drop after a miscommunication with wicketkeeper Alex Carey.
The Indian star regularly flayed the ball away through the offside, taking particular delight against both Green and Nathan Lyon in a 119-run stand with Thakur.
Cummins then cleaned up Umesh Yadav when he bowled him on five to finish with 3-83, while Green (2-44) and Mitchell Starc (2-71) wrapped up the tail.
Scott Boland (2-47) was again close to Australia’s best with the ball, taking the wicket of KS Bharat (five) in the first over on Friday to further strengthen his Ashes claims.
The Victorian seamed the ball back off a good length to take Bharat’s off stump, the kind of ball Steve Smith described on Thursday as being most dangerous in England with Boland’s shorter stature.
Australia expect to have Josh Hazlewood back for the first Test at Edgbaston next Friday.
All eight of Boland’s Tests have come with one of the frontline quicks unavailable but with every over in England he has pushed closer to selection.
Data from analysts CricViz show Boland has delivered 56 per cent of balls on a good line and length in the past three years, a higher ratio than any other Test bowler.
