Any advice on the best way to repair this? Or is this indicative of a larger problem? Trying to figure out where to start.

FOLLOWING. I have a spot like this as well.

Most likely a foundation shifting issue.

Make sure your foundation is watered regularly (daily).

You can buy some ready made concrete in a caulk gun container for easy application.

More pictures please, especially from the sides pushing toward this side?
Floor Plans always help best but hard to find/create ... sigh

Just looking at that pic, I would assume the worst, i.e. foundation shift. If you look closely it appears that there are a few spots that had patchwork mortar reapplied at some point. Look at the inside color differences where there may be other spots that moved previously. I am guessing you are not the original owner. If you are not, you could go back and look at the disclosure statement to see if the previous owner disclosed the issue, if not there could be some legal action warranted depending on the cost of repairs.
