Severity of foundation issue

Can you tell me how concerned I should be on a scale of 1-10 about cracking through cement blocks shown in these photos? They appear at the corner of a home where there is a tuck under a garage. Is this a case where the wall needs to be replaced, or could be repaired. I’m also wondering what the cost for this repair might be. Any ideas?

What did your inspector have to report?
