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

  - A flaw was found within the handling of SMB2 read requests in the kernel ksmbd module. The issue results     from the lack of proper validation of user-supplied data, which can result in a read past the end of an     allocated buffer. An attacker can leverage this to disclose sensitive information on affected     installations of Linux. Only systems with ksmbd enabled are vulnerable to this CVE. (CVE-2023-39179)

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