CVE-2023-26589
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 · uneditedUse after free in some Intel(R) Aptio* V UEFI Firmware Integrator Tools may allowed an authenticated user to potentially enable denial of service 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 confidenceA use-after-free vulnerability in Intel Aptio V UEFI Firmware Integrator Tools allows an authenticated local user to trigger memory corruption leading to denial of service. The vulnerability stems from improper memory management in the firmware integration tool.

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 if Intel Aptio V UEFI Firmware Integrator Tools is installedSearch for the tool in common installation directories such as C:\Program Files\Intel\Aptio V Firmware Integrator or C:\Program Files (x86)\Intel\Aptio V Firmware Integrator, or check the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Aptio V Firmware Integrator for installation evidenceAffected if The tool is found installed on the system
-
Determine the installed version of the toolLocate the executable (typically named FirmwareIntegrator.exe or similar) and check its file properties for the version number, or query the Windows registry for the Version value under the installation keyAffected if The version matches 5.27.03.0003 or 5.27.06.0017
-
Check for recent execution or scheduled usage of the toolReview Windows Event Logs under Application and System logs for Event ID 4688 (process creation) entries related to the firmware integrator executable, or check Task Scheduler for any scheduled tasks running this toolAffected if The tool has been executed recently on the system
-
Monitor for crash or memory corruption eventsCheck Windows Application Event Log for error or crash events (Event ID 1000-1001) involving the firmware integrator process, and review any dump files in C:\Windows\Minidump or the tool's log directoryAffected if Crash dumps or error events related to the tool are present
The system is affected if Intel Aptio V UEFI Firmware Integrator Tools version 5.27.03.0003 or 5.27.06.0017 is installed and the tool is accessible to authenticated local 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 dataApply Intel-provided firmware updates/patches for Aptio V when released; until then, restrict physical and local access to systems running this tool and monitor for anomalous behavior.
