Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - mm/vmemmap/devdax修复了探测 devdax 设备提交 4917f55b4ef9 时的内核崩溃问题 (mm/sparse-vmemmap
    改善复合 devmap 的内存节省添加了对 devdax 设备使用经过优化的 vmmemap 的支持。但 vmemmap 映射的创建方式因架构而异。例如具有哈希转换的 powerpc 在 init_mm 页表中没有 vmemmap 映射而是它们由 vmemmap 优化代码使用的硬件页表中的bolttable 表条目 vmemmap 优化代码使用的 vmemmap_populate_compound_pages() 不识别这些特定于架构的映射。因此允许架构选择此功能。我选择了支持 HUGETLB_PAGE_OPTIMIZE_VMEMMAP 选项的架构因为也支持此功能。此修补程序修复了 ppc64 中的以下崩溃。缺陷无法处理 0xc00c000100400038 处写入的内核数据访问 错误指令地址0xc000000001269d90 Oops不良区域的内核访问sig11 [#1] LE PAGE_SIZE=64K MMU=Hash SMP NR_CPUS=2048 NUMA pSeries Modules 中链接的CPU 7 PID: 1 Commswapper/0 未受感染 6.3.0-rc5-150500.34-default+ #2 5c90a668b6bbd142599890245c2fb5de19d7d28a 硬件名称
