Out-of-bounds read in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via adjacent access.

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.

Improper initialization in the Intel(R) TXT SINIT ACM for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

A flaw was found in computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.

This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition
