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

  - net/mlx5: handle errors in mlx5_chains_create_table() In mlx5_chains_create_table(), the return value of     mlx5_get_fdb_sub_ns() and mlx5_get_flow_namespace() must be checked to prevent NULL pointer dereferences.
    If either function fails, the function should log error message with mlx5_core_warn() and return error     pointer. (CVE-2025-21975)

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