CVE-2023-38587
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 input validation in some Intel NUC BIOS firmware may allow a privileged 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 · low confidenceImproper input validation in Intel NUC BIOS firmware allows a privileged local user to escalate privileges. The vulnerability stems from insufficient validation of input data within the BIOS, potentially allowing authenticated users to execute code at a higher privilege level than intended.

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 the NUC model is among the affected productsCheck the system model via BIOS setup (press F2 during boot), or run `dmidecode -s system-product-name` on Linux, or check System Information on Windows. Match the model name against the list: Nuc8i3behfa, Nuc8i5behfa, Nuc8i5bekpa, Nuc8i7behga, Nuc8i7bekqa, Nuc8i3beh, Nuc8i3bek, Nuc8i5behAffected if The model is one of the eight listed NUC 8 variants
-
Retrieve the installed BIOS firmware versionEnter BIOS setup (F2 at boot) and navigate to the Main or Information page to view the BIOS version, or run `dmidecode -s bios-version` on Linux, or check BIOS version in Windows Device Manager or System InformationAffected if The BIOS version displays as becfl357.0095 exactly
-
Verify the vulnerability conditionCompare your confirmed model and BIOS version against the CVE entry: the affected version for the listed models is becfl357.0095Affected if You have both an affected NUC 8 model AND BIOS version becfl357.0095 installed
You are affected if you own one of the eight listed Intel NUC 8 models and your BIOS firmware is exactly version becfl357.0095.

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-provided BIOS firmware update for affected NUC models. Verify the current BIOS version, download the corresponding patch from Intel's support site, and follow the recommended update procedure including confirming successful flashing and system stability.
