hardware: Side-channel cache attack against DDIO with RDMA

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.

Insufficient memory protection in Intel(R) TXT for certain Intel(R) Core Processors and Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

hw: Machine Check Error on Page Size Change (IFU)

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.
