CVE-2023-42668
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 · uneditedIncorrect default permissions in some onboard video driver software before version 1.14 for Intel(R) Server Boards based on Intel(R) 62X Chipset 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 · high confidenceIncorrect default permissions in the onboard video driver for Intel Server Boards based on Intel 62X Chipset allows an authenticated local user to potentially escalate privileges. The vulnerability exists in driver versions prior to 1.14.

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 the server board modelCheck the system information to confirm the server board is an Intel Server Board based on the Intel 62X Chipset. This can typically be done via system BIOS information, dmidecode output, or vendor documentation.Affected if The system is not an Intel Server Board with 62X Chipset, then this specific CVE does not apply.
-
Locate the onboard video driverIdentify the installed video driver on the system. On Windows, check Device Manager under Display Adapters. On Linux, check via lspci or lsmod for video/graphics drivers.Affected if No Intel onboard video driver is present, the vulnerability does not apply.
-
Determine the driver versionRetrieve the version of the Intel onboard video driver. In Windows, right-click the driver in Device Manager and select Properties > Driver tab. On Linux, use modinfo or check /var/log for driver loading messages.Affected if The driver version cannot be determined or is not the Intel onboard video driver for this chipset.
-
Compare to the affected version rangeCompare the installed driver version to 1.14. Versions prior to 1.14 (such as 1.13.x, 1.12.x, etc.) are affected. Version 1.14 and later are not affected.Affected if The installed driver version is less than 1.14 (for example, 1.13.0 or earlier).
The system is affected if it is an Intel Server Board based on the 62X Chipset with an onboard video driver version installed that is earlier than 1.14.

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 the Intel onboard video driver software to version 1.14 or later to remediate the incorrect default permissions.
