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: devlink: fix netns refcount leak in     devlink_nl_cmd_reload() While preparing my patch series adding netns refcount tracking, I spotted bugs in     devlink_nl_cmd_reload() Some error paths forgot to release a refcount on a netns. To fix this, we can     reduce the scope of get_net()/put_net() section around the call to devlink_reload(). (CVE-2021-47514)

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