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.

A flaw was found in the implementation of Intel Advanced Vector Extensions (AVX) where a local authenticated attacker with the ability to execute AVX instructions is able to gather AVX register state from previous AVX executions.

This could allow information disclosure of AVX register state.

Load value injection in some Intel(R) Processors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
