The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - usbnet: gl620a: fix endpoint checking in genelink_bind() Syzbot reports [1] a warning in usb_submit_urb()     triggered by inconsistencies between expected and actually present endpoints in gl620a driver. Since     genelink_bind() does not properly verify whether specified eps are in fact provided by the device, in this     case, an artificially manufactured one, one may get a mismatch. Fix the issue by resorting to a usbnet     utility function usbnet_get_endpoints(), usually reserved for this very problem. Check for endpoints and     return early before proceeding further if any are missing.
