Oak panel (4X8X1/4) installed over drywall in basement on an inside the basement wall with no cold air or hot air and no moisture behind, has developed a bulge in the right vertical surface about 12″ above the floor and has pulled away from the framing. The panel next to it shows no bulge at this same spot where they meet nor is there any bulge on the other side of the wall in the panel that is directly behind this panel.
Possible causes and solutions.

Why not open it up and take a look? More than likely it'll be moisture related. Otherwise, some possibilities:
Someone shot expanding foam into a hole on exterior wall.
Flatulant wallboard.
Very large critter bored through wall.
Old age sag (hits us all, causing unsightly bulges).
Keep us informed.

If this paneling was installed tight at the joints, then even slight expansion can cause buckling. If there were a weak spot in the adhesive then it would pull away. You say it has pulled away from the framing. Does that imply that it is not glued over solid backing such as drywall? If it is not, then there is probably no sollution, since it will show lumps and dents forever. If it is over solid backing and is glued, you might be able to pull the bump out by nailing it to a stud with a small headed nail. You might be able to pull it tight against the drywall with a drywall anchor of some sort, but of course this will show and need treatment to hide it.
*Bill,Sounds like moisture to me. I vote for taking it off the wall and having a look. You got to replace it anyway.Let us know what you find.Ed. Williams
