CVE-2023-29495
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 for some Intel NUC BIOS firmware before version IN0048 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 · high confidenceImproper input validation in Intel NUC BIOS firmware before version IN0048 allows a privileged local user to escalate privileges. This is a firmware-level vulnerability requiring BIOS update to remediate.

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 exact NUC modelLocate the product label on the NUC chassis or run system information commands: dmidecode -s system-product-name (Linux) or check System Information (Windows). Verify the model is either Nuc8i7inh or Nuc8i5inh.Affected if Model is Nuc8i7inh or Nuc8i5inh
-
Retrieve the current BIOS firmware versionPress F2 during boot to enter BIOS setup and view the BIOS version shown on the main screen, or use command-line tools: dmidecode -s bios-version (Linux) or open Intel NUC Software / System Information in Windows.Affected if Unable to obtain the BIOS version string
-
Compare the installed version to the affected rangeCompare the installed BIOS version string to inwhl357.0049. Versions numerically lower than inwhl357.0049 (such as inwhl357.0048, inwhl357.0047, or earlier) are in the affected range.Affected if Installed version is inwhl357.0048 or any version lower than inwhl357.0049
The system is affected if the NUC model is Nuc8i7inh or Nuc8i5inh and the BIOS firmware version is earlier than inwhl357.0049.

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.
dbcve · scopedUpdate Intel NUC BIOS firmware to version IN0048 or later following vendor update procedures.
BIOS version IN0048 or later (check Intel NUC support page for latest stable release for Nuc8i7inh/Nuc8i5inh)
- Identify the current BIOS version by entering the BIOS setup (F2 during boot) or using Intel's System BIOS Update utility
- Download the latest BIOS update from the Intel NUC product support page for your specific model (Nuc8i7inh or Nuc8i5inh)
- Verify the downloaded update matches your NUC model number exactly
- Create a USB recovery drive following Intel's instructions if required for BIOS update
- Run the BIOS update utility or place the update file on the prepared USB drive
- Reboot the NUC and follow the on-screen prompts to complete the BIOS update
- Do not interrupt power during the BIOS flash process to prevent permanent damage
- After update completes, enter BIOS setup (F2) and verify the new version is IN0048 or later
