CVE-2026-98714
KVM: SVM: Update control fields on #VMEXIT if and only if VMRUN succeeded
Description
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.

Solution
- Apply KVM SVM updates for VMRUN success.
- Ensure control fields are managed correctly on VMRUN failures.
- Review AMD documentation for VMRUN behavior.
- Test changes thoroughly in isolated environments.
