Odd Foundation wall in new home

So we bought a split-entry house that was built in 67 and it has those half height foundation walls in the basement (3' tall). Well today as I was getting some stuff ready to paint I noticed in the family room one wall of that half height basement wall bows/curves in. It has one vertical settling crack in it, but the inspector didn't think that was an issue. I nor the inspector noticed the curved wall (or at least he didn't mention it). I didn't notice it at the time either Basically if I look down the wall it seems the base of the concrete part of the wall curves about 1.5 to 2" into the room before it goes back to normal at the opposing corner. I can't tell if the top is just as bowed.. doesn't seem to be. So basically if you start at one end and and follow the wall it curves into the room about an inch or two in the middle and back out to the other end (so both ends are even and the middle is into the room about an inch-ish). The linoleum which is a beautiful 80s yellow blocky pattern is cut to the curve so lines on the floor make the curve look even worse because they disappear into the curve. The slab floor doesn't seem to be impacted at all. I have only owned this house for a week now, but am a bit sick about this. Should I call someone in? or is this something I should just accept or can I Do anything?
