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.
Time-of-check time-of-use race condition in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.
Gather Date Sampling (GDS) is a transient execution side channel vulnerability affecting certain Intel processor. In this flaw, a local attack using gather instruction (load from memory) may infer stale data from previously used vector registers on the same physical core.
Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially cause a denial of service via local access.
Out-of-bounds write in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.
Improper access control in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.
Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service via local access.
