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

  - smb: client: fix query_info() replay double-free A response-bearing attempt can return a replayable error     and free its response buffer. If SMB2_query_info_init() fails before the next send, cleanup retains the     previous buffer type and frees that response again. Reset response bookkeeping before each attempt to     prevent the stale free. (CVE-2026-64386)

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