严重/漏洞:Linux KVM/x86 shadow MMU 页回收逻辑存在虚拟机逃逸漏洞 漏洞编号:CVE-2026-64561 / PoC 名称:Zapscape 严重等级:严重(KVM 虚拟机逃逸、宿主机内核代码执行) CVSS 分数:无 影响范围: 受影响组件:Linux kernel KVM/x86 legacy shadow MMU 受影响代码路径: arch/x86/kvm/mmu/mmu.c arch/x86/kvm/mmu/paging_tmpl.h 受影响版本: Zapscape (CVE-2026-64561) 涵盖从 f95eec9bed76 (2020-07-08) 到 2abd5287f083 (2026-07-21) 的范围。 受影响功能: KVM/x86 嵌套虚拟化中的 EPT/NPT shadowing、shadow page quota…READ FULL ▾
aim、recursive zap、invalid root 处理及 active_mmu_pages 链表管理。 主要受影响配置: 宿主机启用了 KVM x86 nested virtualization; AMD 环境启用了 SVM/NPT,公开 PoC 不需要额外的 page-walk length 条件; Intel 环境启用了 VMX/EPT,并同时向 L1 暴露 EPT page-walk length 4 和 5; 攻击者在 L1 中具备内核级执行能力;若作为宿主机本地提权使用,则需要能够访问 /dev/kvm。公开 PoC 在 /dev/kvm 为 0666 时可由低权限用户执行; 注意: 当前公开完整利用链依赖目标内核 kconfig、结构体布局、符号偏移和 VMM 内存后端。开启 CONFIG_LIST_HARDENED、CONFIG_DEBUG_LIST 等选项可阻断当前链表写利用,但可能转化为宿主机拒绝服务,不等同于修复漏洞。 漏洞原理 KVM 处理 shadow MMU page fault 时会检查当前 root 是否失效,并在 shadow page 不足时调用 make_mmu_pages_available() 回收旧页。修复前,失效检查发生在回收之前;如果回收使 root 失效,后续 fetch 仍会在该 root 下创建映射。 1. 构造
