CVE-2020-0600
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 · uneditedImproper buffer restrictions in firmware for some Intel(R) NUC may allow an authenticated user to potentially enable escalation of privilege 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 confidenceImproper buffer restrictions in Intel NUC firmware allows an authenticated local user to potentially escalate privileges. This is a memory corruption vulnerability in the firmware layer that can be exploited by a user with local access to the system.

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 the Intel NUC modelCheck the system label on the chassis or use system information utilities (such as 'systeminfo' on Windows or 'dmidecode' on Linux) to determine the exact model number (e.g., Nuc8cchkr, Nuc7cjyh, Nuc6cayh, De3815tykhe).Affected if The model matches any of the affected products listed in the CVE.
-
Determine the current firmware versionAccess the BIOS/UEFI setup during boot and check the firmware version under the 'Advanced' or 'Main' tab, or use Intel's firmware update utility or command-line tools (such as 'fwupd' or manufacturer-provided tools) to query the installed firmware version.Affected if The firmware version cannot be determined or is lower than the version thresholds for the detected model.
-
Compare against version thresholdsMatch your detected firmware version to the affected version range: for Nuc8cchkr/Nuc8cchb look for < chaplcel.0047; for Nuc7cjysal/Nuc7cjyh/Nuc7pjyh look for < jyglkcpx.86a.0053; for Nuc6cays/Nuc6cayh look for < ayaplcel.86a0053; for De3815tykhe look for < tybyt20h.86a.0024.Affected if The installed version is below the specified threshold for your specific model.
-
Verify local authenticated access existsConfirm whether local user accounts with valid credentials exist on the system, as the vulnerability requires an authenticated local user to exploit the memory corruption.Affected if Local user accounts are present on the system (the vulnerability requires authenticated local access).
The system is affected if it is an Intel NUC model listed in the CVE with firmware version below the specified threshold and local user authentication is configured.

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 dataApply the Intel firmware update for affected NUC products. Verify all credentials and access controls are reviewed following the patch, as the vulnerability requires authenticated local access.
