CVE-2022-24382
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 firmware for some Intel(R) NUCs 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 analysisThe application accepts input without confirming it is well-formed or within expected bounds, so malformed data can push the program into states its author never anticipated. Attackers probe these gaps to trigger crashes, bypass logic, or feed tainted values into more dangerous operations downstream. Remediating it well means validating and normalising every input at the boundary against a strict allow-list — not merely filtering known-bad values.

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 · scopedFirmware >= bctgl357.0065 (Lapbc510/Lapbc710), >= kctgl357.0040 (Lapkc71x/Lapkc51e), or >= dbtgl579.0055 (Nuc11 series)
- 1. Identify the specific Intel(R) NUC or Lap model from the affected product list (Lapbc510, Lapbc710, Lapkc71f, Lapkc71e, Lapkc51e, Nuc11dbbi9, Nuc11dbbi7, or Nuc11btmi7)
- 2. Navigate to the Intel Support website or the specific product page for your device
- 3. Locate the BIOS/Firmware download section for your model
- 4. Download the firmware update that matches or exceeds: bctgl357.0065 for Lapbc510/Lapbc710, kctgl357.0040 for Lapkc71f/Lapkc71e/Lapkc51e, or dbtgl579.0055 for Nuc11dbbi9/Nuc11dbbi7/Nuc11btmi7
- 5. Follow Intel's standard firmware update procedure - typically this involves running the BIOS update utility from Windows or creating a USB recovery drive
- 6. Ensure the device remains powered throughout the update process to avoid permanent damage
- 7. After update completion, verify the firmware version matches the target version
