Am looking at all the latest patches and updates in light of new vulnerabilities in all modern CPUs discovered just this week. While doing so, ran into this issue noted on Intel sight and referenced on HP-
HPSBHF03571 rev 2 - Intel Management Engine Cumulative Security update and fix for WPA2 vulnerability
Have downloaded and run associated Discovery Tool and received following output:
Tool Started 1/5/2018 5:11:01 PM
Name: PAUL-PC
Manufacturer: HP-Pavilion
Model: NY591AA-ABA p6267c
Processor Name: Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz
OS Version: Microsoft Windows 10 Home
Status: Detection Error: This system may be vulnerable, either the Intel(R) MEI/TXEI driver is not installed (available from your system manufacturer) or the system manufacturer does not permit access to the ME/TXE from the host driver.
Tool Stopped
I have also used HP Support Assistant - Maintain - Sofware Updates which states:
Based on the last analysis, your computer is up to date and there are no alerts or tips from HP.
So what am I to conclude?
I am vulnerable or not??
I need the patch or not??
Not sure if this is a BIOS fix, but if I need the patch, is the install process pretty reliable?
I don't want to brick the machine -- not sure I know how to recover that.
Thanks for any insights
Paul

I suggest that you review the Intel write up about the exposure and how someone could exploit the issue on different PCs even if your PC is not affected according to the information that I posted for you to review and then determine on your own if your PC has the exposure.

Hi,
Your PC is 7+ years old and HP may not be providing assistance for all products that are outside of the support period.
Please post the version of the Intel Detection tool that you used.
The security flaw according to this article affects newer processors.

The Intel Detection Tool I used is:
Intel-SA-00086-CLI Version 1.0.0.152 filename: Intel-SA-00086-console.exe
The best answer would be that my processor is not affected.
My CPU is: Intel(R) Core(TM)2 Quad CPU Q8300@2.5 GHZ 4 CPUs
I also wondered if the compromised subsystem was more an enterprise capability that might not concern home workstations.
With so many recent vulnerabilities discovered, it is difficult to decide what one must do to perform due diligence.
You mentioned my system is 7+ years old and may be beyond the support period. I certainly would not expect HP
to continue providing general support, but might hope that in the case of severe security risks, still cover those types
of issues. E.g., I think Microsoft even recently put out an XP update/patch due to a severe security exposure.
Otherwise, these "old" systems could effectively become unsafe to use in any capacity. I am
not the latest tech junkie and find my 7+ year old quad processor working more than adequate for my needs.
Thank-you for taking time to help me assess this issue.
