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

  - wifi: iwlwifi: mld: validate sta_mask before ffs() in BA session handlers Three BA session handlers use     ffs(ba_data->sta_mask) - 1 to derive a station ID without checking that sta_mask is non-zero. When     sta_mask is zero, ffs() returns 0 and the subtraction wraps to 0xFFFFFFFF, causing an out-of-bounds access     on fw_id_to_link_sta[]. Add WARN_ON_ONCE(!ba_data->sta_mask) guards before each ffs() call, consistent     with the existing check in iwl_mld_ampdu_rx_start(). (CVE-2026-64255)

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