Description
An issue has been found in KVM before 5.5.7, where vmx_check_intercept ws is not yet fully implemented on Intel processors, causing e.g. the I/O or MSR interception bitmaps not to be checked. This in turn allowed the L2 guest to trick the L0 hypervisor into accessing sensitive information on the L1 hypervisor.
