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

  - net/mlx5: Fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list mlx5_query_nic_vport_mac_list() sizes     its firmware command buffer using the PF's log_max_current_uc/mc_list capabilities. When querying a VF     vport with a larger configured max (via devlink), the firmware response can overflow this buffer: BUG:

Refactor the function to allocate and return the MAC     list internally, removing the caller's dependency on knowing the correct max. (CVE-2026-53230)
