  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: nSVM: Triple fault if restore host CR3 fails on nested #VMEXIT\n\nIf loading L1's CR3 fails on a nested #VMEXIT, nested_svm_vmexit()\nreturns an error code that is ignored by most callers, and continues to\nrun L1 with corrupted state. A sane recovery is not possible in this\ncase, and HW behavior is to cause a shutdown. Inject a triple fault\ninstead, and do not return early from nested_svm_vmexit(). Continue\ncleaning up the vCPU state (e.g. clear pending exceptions), to handle\nthe failure as gracefully as possible.\n\nFrom the APM:\n\n  Upon #VMEXIT, the processor performs the following actions in order to\n  return to the host execution context:\n\n  ...\n\n  if (illegal host state loaded, or exception while loading host state)\n      shutdown\n  else\n      execute first host instruction following the VMRUN\n\nRemove the return value of nested_svm_vmexit(), which is mostly\nunchecked anyway.",
