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

  - cifs: validate DFS referral string offsets parse_dfs_referrals() validates that the response header and     referral array fit in the received buffer, but each referral also contains string offsets supplied by the     server. Those offsets are used to compute the DfsPath and NetworkAddress string pointers without checking     whether they still point inside the response buffer. A malformed referral can therefore make the computed     pointer exceed the end of the buffer. The resulting negative max_len is then passed to     cifs_strndup_from_utf16(), and the non-Unicode path forwards it to kstrndup() as a size_t, allowing     strnlen() to read out of bounds. Validate each string offset before deriving the string pointer.
    (CVE-2026-72318)

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