CVE-2021-0056
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 · uneditedInsecure inherited permissions for the Intel(R) NUC M15 Laptop Kit Driver Pack software before updated version 1.1 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 confidenceThe Intel NUC M15 Laptop Kit Driver Pack before the updated version contains insecure inherited file system permissions that allow an authenticated local user to modify or overwrite privileged executable files, enabling local privilege escalation.

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 system modelCheck if the target system is an Intel NUC M15 Laptop Kit (model Lapbc510 or Lapbc710) by running 'systeminfo' or checking BIOS/UEFI informationAffected if System is NOT an Intel NUC M15 Laptop Kit model Lapbc510 or Lapbc710, then not affected by this specific CVE
-
Check firmware versionAccess UEFI/BIOS setup on the Intel NUC M15 or use 'fwupdmgr get-version' if available, and identify the Intel Lapbc510 or Lapbc710 firmware versionAffected if Firmware version is less than 1.1 (e.g., 1.0.x or earlier) for either Lapbc510 or Lapbc710, indicating vulnerability to this CVE
-
Verify driver pack installationCheck for installed Intel NUC M15 Laptop Kit Driver Pack by looking in Program Files/Program Files (x86) for Intel driver packages, or query the Windows Registry under HKLM\SOFTWARE\Intel for driver pack informationAffected if Driver Pack is installed and version cannot be determined or is prior to the patched release containing fixed permissions
-
Examine file permissions on driver executablesIf the driver pack is installed, inspect file permissions on executable files in the driver pack directories (e.g., any .exe or .sys files in the Intel driver installation folder) using 'icacls' or File Explorer Properties > SecurityAffected if Authenticated users or non-admin accounts have Write or Modify permissions on privileged executable files in the driver pack, indicating the insecure permission vulnerability exists
The system is affected if it is an Intel NUC M15 Laptop Kit (Lapbc510 or Lapbc710) with firmware or driver pack version prior to 1.1, where low-privilege users can modify privileged executables due to insecure file permissions.
