Description

Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation (eIBRS) capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer (RSB) prediction.
