Intel ID: INTEL-SA-00240
Advisory Category: Hardware
Impact of vulnerability: Escalation of Privilege
Severity rating: HIGH
Original release: 11/12/2019
Last revised: 11/12/2019

Summary: 

Potential security vulnerabilities in System Management Mode (SMM) and Intel® Trusted Execution Technology (TXT) for some Intel® Core™ Processors and Intel® Xeon® Processors may allow escalation of privilege, denial of service or information disclosure.  Intel is releasing firmware updates to mitigate these potential vulnerabilities.

Vulnerability Details:

CVEID: CVE-2019-0152
