CVE-2024-29216
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 · uneditedExposed IOCTL with insufficient access control issue exists in cg6kwin2k.sys prior to 2.1.7.0. By sending a specific IOCTL request, a user without the administrator privilege may perform I/O to arbitrary hardware port or physical address, resulting in erasing or altering the firmware.
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 cg6kwin2k.sys Windows kernel driver exposes an IOCTL interface with insufficient access control checks. Prior to version 2.1.7.0, unprivileged users can send specific IOCTL requests to perform direct I/O operations to arbitrary hardware ports or physical addresses, enabling potential firmware erasure or alteration.

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.
-
Locate the driver file on the systemSearch for cg6kwin2k.sys in the Windows\System32\drivers directory and subdirectories: dir /s C:\Windows\System32\drivers\cg6kwin2k.sysAffected if The file exists on the system, indicating the driver is installed
-
Retrieve the driver file versionRight-click the driver file, select Properties, then go to the Details tab and check the Product Version field, or use PowerShell: (Get-Item 'C:\Windows\System32\drivers\cg6kwin2k.sys').VersionInfo | Select-Object ProductVersionAffected if The version is lower than 2.1.7.0 or the version field is empty or unreadable
-
Check if the driver is currently loadedRun 'sc query cg6kwin2k' in Command Prompt or use PowerShell: Get-Service -Name cg6kwin2k -ErrorAction SilentlyContinueAffected if The driver service exists and shows a RUNNING state, meaning the IOCTL interface is active
-
Verify driver file digital signatureRight-click the driver file, select Properties, then go to the Digital Signatures tab to confirm the file is signed by the expected vendorAffected if The file is unsigned or signed by an unrecognized publisher, suggesting a potentially tampered or malicious version
The system is affected if cg6kwin2k.sys exists with a version lower than 2.1.7.0 and the driver service is currently running, exposing the vulnerable IOCTL interface to unprivileged users.

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.
From vendor dataUpgrade cg6kwin2k.sys to version 2.1.7.0 or later which contains proper access control validation for the IOCTL handler. Prior to patching, restrict driver access and monitor for suspicious I/O requests.
