hw: cpu: information disclosure via Intel Software Guard Extensions (SGX) Platform

Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with SGX may allow an unprivileged user to potentially enable information disclosure via physical access.

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

Improper input validation for some Intel(R) PROSet/Wireless WiFi, Intel vPro(R) CSME WiFi and Killer(TM) WiFi products may allow unauthenticated user to potentially enable denial of service via local access.

kernel: hw: Insecure default variable initialization for the Intel BSSA DFT feature

Insecure default variable initialization for the Intel BSSA DFT feature may allow a privileged user to potentially enable an escalation of privilege via local access.
