CVE-2022-38396
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 · uneditedHP Factory Preinstalled Images on certain systems that shipped with Windows 10 versions 20H2 and earlier OS versions might allow escalation of privilege via execution of certain files outside the restricted path. This potential vulnerability was remediated starting with Windows 10 versions 21H2 on October 31, 2021.
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 confidenceHP factory preinstalled images on systems shipped with Windows 10 versions 20H2 and earlier contain a local privilege escalation vulnerability that allows execution of certain files outside a restricted path. This bypasses intended access controls to achieve elevated privileges. The vulnerability was patched in Windows 10 version 21H2 released October 31, 2021.

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.
-
Check Windows 10 version build numberRun 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to see the installed Windows 10 build and versionAffected if The build number corresponds to Windows 10 1909 or earlier (e.g., builds 18362, 18363, 17763, 17134, etc.) - these are all versions 20H2 and earlier and are affected
-
Check Windows 10 release name and buildRun 'reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v DisplayVersion' to get the release name (e.g., 1909, 1809, 1709)Affected if The DisplayVersion value is 1909 or any earlier release (1507, 1511, 1607, 1703, 1709, 1803, 1809)
-
Verify if system is Windows 10 21H2 or laterCheck if the installed version is Windows 10 version 21H2 or later by running 'systeminfo' and reviewing the OS Name and Version fieldsAffected if The system is NOT running Windows 10 21H2 or later - if it shows 21H2, 22H2, or later, the vulnerability is patched
-
Confirm system is HP with factory imageCheck system manufacturer by running 'wmic computersystem get manufacturer' or checking BIOS/system informationAffected if The system is an HP machine with a factory-preinstalled Windows 10 image from versions 20H2 or earlier - this context makes the vulnerability applicable
-
Check current build against known vulnerable buildsRun 'ver' command or check HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CurrentBuild to get the numeric buildAffected if The numeric build is 19041 (20H2) or lower - builds below 19041 are in the vulnerable range
A system is affected if it runs Windows 10 version 21H2 or earlier (build 19041 or lower), particularly on HP hardware with factory-preinstalled images from versions 20H2 and earlier.

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 · scopedUpgrade affected systems to Windows 10 version 21H2 or later, or rebuild factory images with updated Windows versions to prevent the vulnerability on newly deployed systems.
Windows 10 version 21H2 or later
- Verify current Windows 10 version by opening Settings > System > About
- Back up all critical data and files before proceeding
- Open Windows Update (Settings > Update & Security > Windows Update) and check for updates
- If Windows 10 21H2 or later is not available via Windows Update, use the Microsoft Media Creation Tool from https://www.microsoft.com/en-us/software-download/windows10 to create installation media
- Run the media creation tool and select 'Upgrade this PC now' to install Windows 10 21H2 or later
- Follow the on-screen prompts to complete the upgrade process
- After upgrade, verify the new version by checking Settings > System > About (should show version 21H2 or later)
