Wikipedia article on the Winter War
The 3 top Soviet officers (apart from Stalin):
Kliment Voroshilov: died 2 December 1969.
Semyon Timoshenko: died 31 March 1970.
Kirill Meretskov: died 30 December 1968.

The claim is false.

Other records suggest that Commander (kombrig) Alexei Vinogradov was sentenced in January 1940 to the Highest Degree of Punishment (VMN) by the Military Tribunal of the 9th Army along with his chief of staff Onufri Volkov. On January 11 he was publicly executed in front of [the] formation.
