CVE-2026-23401 KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE When installing an emulated MMIO SPTE, do so after dropping/zapping the existing SPTE if it's shadow-present. While commit a54aa15c6bda3 was right about...

CVE-2026-23401

CVE-2026-23401: In the Linux kernel KVM x86/mmu, a race allowed installing an MMIO SPTE without first zapping an existing shadow-present SPTE when guest memory writes occurred outside KVM’s scope. This could enable a guest‑memory–related fault to leave a shadow SPTE intact when an MMIO SPTE is in...
