Improper conditions check in the voltage modulation interface for some Intel(R) Xeon(R) Scalable Processors may allow a privileged user to potentially enable denial of service via local access.

Insufficient input validation in system firmware for Intel(R) Xeon(R) Scalable Processors, Intel(R) Xeon(R) Processors D Family, Intel(R) Xeon(R) Processors E5 v4 Family, Intel(R) Xeon(R) Processors E7 v4 Family and Intel(R) Atom(R) processor C Series may allow a privileged user to potentially enable escalation of privilege, denial of service and/or information disclosure via local access.

Insufficient access control in system firmware for Intel(R) Xeon(R) Scalable Processors, 2nd Generation Intel(R) Xeon(R) Scalable Processors and Intel(R) Xeon(R) Processors D Family may allow a privileged user to potentially enable escalation of privilege, denial of service and/or information disclosure via local access.

A race condition in specific microprocessors using Intel (R) DDIO cache allocation and RDMA may allow an authenticated user to potentially enable partial information disclosure via adjacent access.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.
