Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - net/mlx5シャットダウンフローでの ECVF vports アンロードを修正。BlueField デバイスの組み込みチップECVFで仮想関数が作成される際のシャットダウンフロー UAF を修正します。このような場合、vport acl 入力テーブルは適切に破壊されません。ECVF機能はecpf_vport_exists機能に依存していません。したがって、ECVF vportの有効化/無効化時に関数mlx5_eswitch_(enable|disable)_pf_vf_vports()はこれをテストしません。

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 ECVF vports unload on shutdown flow Fix shutdown flow UAF when a virtual function is created     on the embedded chip (ECVF) of a BlueField device. In such case the vport acl ingress table is not     properly destroyed. ECVF functionality is independent of ecpf_vport_exists capability and thus functions     mlx5_eswitch_(enable|disable)_pf_vf_vports() should not test it when enabling/disabling ECVF vports.
