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: efi/fdt: fix panic when no valid fdt     found setup_arch() would invoke efi_init()->efi_get_fdt_params(). If no valid fdt found then     initial_boot_params will be null. So we should stop further fdt processing here. I encountered this issue     on risc-v. (CVE-2021-47134)

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