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 · unedited
Improper input validation in BIOS firmware for some Intel(R) NUC 11 Compute Elements before version EBTGL357.0065 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 confidence

Improper input validation in the BIOS firmware of Intel NUC 11 Compute Elements allows a privileged local user to potentially escalate privileges. The vulnerability exists in versions prior to EBTGL357.0065 and stems from insufficient validation of input within the BIOS environment.

MitigationUpdate BIOS firmware to version EBTGL357.0065 or later on all affected Intel NUC 11 Compute Elements.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the NUC model
    Check the product label on the device or use system information tools (such as dmidecode -s system-product-name or Intel System Discovery) to determine the exact model number
    Affected if The model is not one of the listed affected products (Cm11ebi38w, Cm11ebc4w, Cm11ebi58w, Cm11ebv58w, Cm11ebi716w, Cm11ebv716w, Nuc11dbbi9, Nuc11dbbi7)
  2. Retrieve the current BIOS version
    Enter the BIOS setup (press F2 during boot) and navigate to the Main or Information page, or use the command 'dmidecode -s bios-version' in Linux, or check via Intel Platform Flash Tool or Intel NUC Software Studio
    Affected if Unable to retrieve a BIOS version (firmware may be corrupted or inaccessible)
  3. Compare the BIOS version against the fixed version
    Check if the installed BIOS version string is lower than EBTGL357.0065. Note that version strings may appear as ebtgl357.0065 or similar formats
    Affected if The installed BIOS version is any version prior to EBTGL357.0065 (for example, ebtgl357.0042, ebtgl357.0050, or earlier)
  4. Verify the BIOS is the original vendor firmware
    Confirm the BIOS was not modified or downgraded from a later patched version. Check the BIOS build date in the BIOS setup Information page
    Affected if The BIOS has been rolled back to a version earlier than EBTGL357.0065 after a patch was applied

The system is affected if it is an Intel NUC 11 Compute Element (Cm11ebi38w, Cm11ebc4w, Cm11ebi58w, Cm11ebv58w, Cm11ebi716w, Cm11ebv716w) or NUC11dbbi9/7 and the installed BIOS version is earlier than EBTGL357.0065

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update BIOS firmware to version EBTGL357.0065 or later on all affected Intel NUC 11 Compute Elements.

Recommended fix High confidence

EBTGL357.0065

  1. Identify your exact NUC 11 model number (e.g., Cm11ebi38w, Nuc11dbbi9, etc.)
  2. Visit Intel's support website and search for your specific NUC model
  3. Download the BIOS firmware update package version EBTGL357.0065 or later
  4. Extract the downloaded BIOS update files to a USB flash drive
  5. Connect the USB drive to the NUC 11 device
  6. Restart the NUC and enter the BIOS setup (typically by pressing F2 during boot)
  7. Navigate to the BIOS update/flash utility (often under 'Security' or 'Advanced' menu)
  8. Select the BIOS update file from the USB drive and initiate the update
Caveat BIOS firmware updates carry risk of permanent damage if interrupted; ensure stable power and do not interrupt the flashing process
