Best thing to do is go to a flooring place and see if they have anything to fix it. But as far as I know, there's no product out there. You could try to put some flooring adhesive on the back side and glue back in place. Hopefully, it is not noticable, if there is a design on it. It is sometimes easier to hide, with putting some crazy glue across the top cut part.
