CVE-2020-8675
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsufficient control flow management in firmware build and signing tool for Intel(R) Innovation Engine before version 1.0.859 may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInsufficient control flow management in the Intel Innovation Engine firmware build and signing tool allows an unauthenticated user with physical access to potentially escalate privileges. The vulnerability exists in versions before 1.0.859 and stems from improper control flow handling during the firmware build and signing process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Intel Innovation Engine is presentCheck system firmware or BIOS information for Intel Innovation Engine (IE) component. On Intel-based systems, this can often be verified via 'dmidecode -t processor' or by checking BIOS/UEFI setup screens under advanced chipset or Intel settings.Affected if The system has Intel Innovation Engine firmware installed (not all systems have this component).
-
Locate the Innovation Engine firmware versionAccess the IE firmware version through the system's BIOS/UEFI interface (often under 'Intel Management Engine', 'Intel Innovation Engine', or similar chipset firmware settings), or use system information tools provided by the OEM that report platform firmware versions.Affected if The version cannot be determined from available system tools - if IE is present but version is hidden or inaccessible, assume potentially affected.
-
Compare installed version against 1.0.859If the IE firmware version is visible in BIOS settings, system diagnostics, or OEM-provided firmware update utilities, compare the numeric version to 1.0.859.Affected if The installed IE firmware version is below 1.0.859 (for example, 1.0.842, 1.0.751, etc.).
A system is affected if it contains Intel Innovation Engine firmware and the installed version is lower than 1.0.859, combined with the requirement of physical access for exploitation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.0.859
Upgrade the Intel Innovation Engine firmware to version 1.0.859 or later. This typically requires applying a BIOS/firmware update from the system OEM, as the Innovation Engine firmware is delivered through platform firmware updates.
