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 directory replay double-free A response-bearing attempt can return a replayable     error and free its response buffer. If SMB2_query_directory_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-2026-64387)

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