Kernel: kvm: nVMX: L2 guest may trick the L0 hypervisor to access sensitive L1 resources

A flaw was found in the way KVM hypervisor handled instruction emulation for the L2 guest when nested=1 virtualization is enabled. In the instruction emulation, the L2 guest could trick the L0 hypervisor into accessing sensitive bits of the L1 hypervisor. An L2 guest could use this flaw to...
