  "details": "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 state. A sane recovery is not possible in this case, and HW behavior is to cause a shutdown. Inject a triple fault instead, and do not return early from nested_svm_vmexit(). Continue cleaning up the vCPU state (e.g. clear pending exceptions), to handle the failure as gracefully as possible.  From the APM:    Upon #VMEXIT, the processor performs the following actions in order to   return to the host execution context:    ...    if (illegal host state loaded, or exception while loading host state)       shutdown   else       execute first host instruction following the VMRUN  Remove the return value of nested_svm_vmexit(), which is mostly unchecked anyway.",
