A sphere?
a sphere has no bases and it only has one curved surface
The solid figure you're describing is a cylinder. It has two circular bases, but if we consider a cylinder without its bases, it consists of a single curved surface wrapping around the height of the cylinder. Another example of a solid figure with one curved surface and no bases is a cone if we only consider the curved part without the base.

Cylinder - a solid figure formed by two congruent parallel circles joined by a curved surface.

A figure with 2 circular bases and one curved surface is called a cylinder. Examples are food cans.

It's a rectangle.
A cylinder has 3 faces: two circular bases and one curved surface. It has 2 edges where the bases meet the curved surface. In terms of vertices, a cylinder has 0 vertices, as there are no sharp corners.
A cylinder has 2 equal parallel flat surface circular bases and a curved surface body.
