It's pretty obvious that Karin must know that Naruto is an Uzumaki, because "Naruto Uzumaki" is a world renowned hero,and everybody knows his name.So if she somehow didn't know that he is an Uzumaki prior of the war, she definitely knew after.Naruto was also renowned before the war, since he was the Hero of Konoha after defeating Pain. It's unknown if Naruto knows the other way around, because as far as we know, the only time they interacted was when they were taking Karin to the leaf after Sasuke vs Danzo, and they didn't even talked back then.Also, nobody ever referred to Karin as "Karin Uzumaki".Not even Sasuke knew that Karin was an Uzumaki until Kabuto (i think) told him.
