The 34-year-old Tigers tighthead - who was not included in Brian Ashton's RBS 6 Nations squad after pulling out of last autumn's World Cup - has been charged with punching or striking Leinster's Ireland lock Malcolm O'Kelly in the Guinness Premiership side's 25-9 win at Welford Road.
White must now face an independent disciplinary commission on an as yet unspecified date, along with the Exiles trio - replacement prop Dan Murphy, second-row Bob Casey and flanker Declan Danaher.
Murphy is accused of tripping Treviso prop Salvatore Costanzo in the sides' match at Stadio Comunale di Monigo, which the Exiles won 24-11, while Casey and Danaher have both been charged with stamping - on lock Cornelius van Zyl in the latter's case.
