Can lightlike geodesics cross an event horizon?

Isn't the event horizin defined as the point where they can't?

they can only either enter or leave, but not both.

I ask because it seems like the curvature goes infinite at the event horizon, not the singularity.
Which implies that even a photon directly incident on the event horizon should fail to cross it in finite time.
