Only in a mundane and conventional sense, but Flash is neither mundane nor conventional.
Superman, despite all his powers, is still a physical being in many ways constrained by physics. He moves through time linearly, he moves through space corporally, he can succumb to physical force (Doomsday), he is affected by radiation (sunlights & kryptonite), he is made of molecules and physical matter, so on and so forth. This allows Flash to dismantel him any number of ways.
- Go back in time
- Banish him to the Speed Force
- Rain a hail of Infinite Mass Punches upon him
- Fetch Kryptonite or put him under a red sun
- Phase him into the ground
etc.
Now we could argue Flash possesses any number of weaknesses while standing still, but the key point to the fight is that Flash is magnitudes upon magnitudes faster than Superman, enabling him to take advantage of any one of those weaknesses before Superman could even think of attempting to use one of Flash's.
Speed kills.
This isn't a mere "could" scenario under idealized circumstances like with Batman or- frankly- ANY rube with a chunk of Kryptonite... under those contrived scenarios, the two are always on unequal ground, Batman impossibly getting the jump on Superman and Superman not using his abilities to their utmost. Flash vs Supes is not the same, because in a case where they are equally aware, equally violent, and start at the same time, Flash is always able to win, unlike Batman w/ Kryptonite. Why?
