You can find all the out of box RQM widgets from here:

There is no widget which would provide the info you want. The closest widget could be be adding an Execution query widget or test matrix widget for which you need to define a query in TCER view. In TCER view, you can have last result and defect columns. But these two widgets will get count of defects with no defect details unless you click on the query jumping to TCER view. You may consider to use Report Builder to create a custom report in your case.
