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。

  - mm/vmemmap/devdax修正探測 devdax 裝置提交 4917f55b4ef9 時發生的核心損毀 (mm/sparse-vmemmap
    改善複合 devmaps 的記憶體節省) 已新增支援針對 devdax 裝置使用最佳化 vmmemap。但 vmemmap 對應的建立方式需視架構而定。例如具有雜湊轉譯的 powerpc 在 init_mm 頁面表格中沒有 vmemmap 對應它們只是硬體頁面表格中的bolted 表格項目vmemmap 最佳化程式碼所使用的 vmemmap_populate_compound_pages() 無法感知這些架構特定的對應。因此允許架構選擇此功能。我選取了支援 HUGETLB_PAGE_OPTIMIZE_VMEMMAP 選項的架構因為也支援此功能。此修補程式可修正 ppc64 的下列損毀問題。錯誤寫入 0xc00c000100400038 時無法處理核心資料存取錯誤指令位址0xc000000001269d90 Oops錯誤區域的核心存取信號11 [#1] LE PAGE_SIZE=64K MMU=Hash SMP NR_CPUS=2048 NUMA pSeries 模組連結於7 PID1 通訊swapper/0 未受污染的 6.3.0-rc5-150500.34-default+ #2 5c90a668b6bbd142599890245c2fb5de19d7d28a 硬體名稱
