CVE-2026-46032

CVE-2026-46032 concerns the Linux kernel KVM/nSVM path. When restoring host CR3 fails during a nested #VMEXIT, nested_svm_vmexit() returns an error code that can be ignored, allowing L1 to run with corrupted state. The documented mitigation is to inject a triple fault and avoid returning early fr...

PT-2026-43899

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Triple fault if restore host CR3 fails on nested VMEXIT If loading L1's CR3 fails on a nested VMEXIT, nested svm vmexit returns an error code that is ignored by most callers, and continues to run L1 with corrupted stat...

CVE-2025-40038

CVE-2025-40038 affects the Linux kernel KVM/SVM fastpath handling. The vulnerability arises when VM-Exit handling attempts to decode and emulate an instruction to skip WRMSR/HLT fastpaths if the next RIP is not valid, which can require reading guest memory. Reading guest memory via the emulator c...
