Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Fix memory leak in     margining Memory for the usb4->margining needs to be relased for the upstream port of the router as well,     even though the debugfs directory gets released with the router device removal. Fix this. (CVE-2023-53050)

Note that Nessus relies on the presence of the package as reported by the vendor.
