CVE-2020-8767
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 · uneditedUncaught exception in the Intel(R) 50GbE IP Core for Intel(R) Quartus Prime before version 20.2 may allow an authenticated user to potentially enable denial of service via local 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 confidenceUncaught exception in Intel 50GbE IP Core for Quartus Prime allows an authenticated local user to cause denial of service. The vulnerability exists in versions prior to 20.2 and triggers when the exception is not properly handled, potentially causing the IP core or system to become unavailable.

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.
-
Identify Quartus Prime installation versionRun 'quartus_sh --version' or check the Quartus Prime installation directory for the version file, typically found in the main Quartus installation folderAffected if Version number returned is below 20.2 (for example, 20.1, 19.4, 18.1)
-
Locate FPGA design files using 50GbE IP CoreSearch project directories for .qip or .ip files referencing the 50GbE IP Core, or open Quartus Prime projects and check the IP Catalog for instantiated 50GbE componentsAffected if Any .qip, .ip, or design file contains instantiation of the Intel 50GbE IP Core
-
Confirm IP Core version in projectOpen the Quartus project in Quartus Prime, navigate to IP Components panel, locate the 50GbE IP Core instance, and check the IP variation file for the version usedAffected if The IP Core version shown is earlier than the version bundled with Quartus Prime 20.2
-
Check for unhandled exception triggersReview design documentation or timing reports for 50GbE IP Core configuration; examine if error handling logic is implemented in the surrounding logicAffected if No custom error handling logic surrounds the 50GbE IP Core and design uses default configuration
User is affected if Quartus Prime version is below 20.2 and any deployed FPGA design contains the 50GbE IP Core without vendor-supplied patches or updated IP version.

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 data20.2
Upgrade Intel Quartus Prime to version 20.2 or later to obtain the patched 50GbE IP Core. Re-implement and redeploy any FPGA designs using the vulnerable IP core version.
