The bug was about dirty video files. If the system vulnerability is patched the USB that caused the DOS should not be able to cause it again. Video files often have UI controls written into them. This is technically not malware, but something that has the potential to be malware. You should be fine to run the USB again. Save your session before you do, and don't sudo to use the USB. There is a chance that the USB will no longer work for you too.
