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.

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.

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.

A flaw was found in Intel® VT-d products. Entries from the context cache on some types of context cache invalidations may not be properly invalidated which may allow an authenticated user to potentially enable escalation of privilege via local access. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable denial of service via adjacent access.
