Summary

The Linux kernel KVM SVM code updates control fields on #VMEXIT even when VMRUN fails, although AMD does not guarantee what the processor does after a VMRUN failure. The actions requested in those control fields may therefore not have been performed. The Linux kernel from 2.6.38 is affected.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Update control fields on #VMEXIT if and only if VMRUN succeeded Leave control.erap_ctl and control.clean as-is in the VMCS if VMRUN fails, because as per AMD: there's no explicit architectural guarantee about the behavior in the presence of VMRUN failures. So the best thing to do would be to assume that if VMRUN fails, the actions requested in the control fields may not have been performed.
