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: iommu/vt-d: Remove WO permissions on     second-level paging entries When the first level page table is used for IOVA translation, it only supports     Read-Only and Read-Write permissions. The Write-Only permission is not supported as the PRESENT bit     (implying Read permission) should always set. When using second level, we still give separate permissions     that allows WriteOnly which seems inconsistent and awkward. We want to have consistent behavior. After     moving to 1st level, we don't want things to work sometimes, and break if we use 2nd level for the same     mappings. Hence remove this configuration. (CVE-2021-47035)

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