Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - RDMA/irdma將 MSIX 用來在線上 CPU + 1 上限 irdma 驅動程式可使用等於 num_online_cpus() + 1 的 msix 向量數量上限如果超過該數量則會在下方顯示核心警告堆疊。驅動程式嘗試使用大於 CPU ID 上限的 CPU 遮罩更新相似性提示時核心會擲回警告。藉由將 MSIX 向量設定為 num_online_cpus() + 1 的上限修正此問題。警告include/linux/cpumask.h:106 的 CPU: 7 PID: 23655 irdma_cfg_ceq_vector+0x34c/0x3f0 [irdma] RIP
