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 next_buffer UAF and NextCommand bounds in compound PDUs Fix several related bounds     checking and pointer lifecycle issues in receive_encrypted_standard()'s handling of compound encrypted     frames: - Clear next_buffer after assigning it to server->bigbuf. A stale next_buffer pointer can lead to     a use-after-free on subsequent error paths. - Update pdu_length to the decrypted plaintext size     (buf_size). Using the pre-decryption length allows NextCommand to point into stale ciphertext residue. -     Reject next_cmd values smaller than MID_HEADER_SIZE(server). - Fix an integer overflow in the upper bound     check by verifying pdu_length - next_cmd < MID_HEADER_SIZE(server), ensuring the trailing slice is large     enough for a header. (CVE-2026-98171)

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