CVE-2023-22305
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 · uneditedInteger overflow in some Intel(R) Aptio* V UEFI Firmware Integrator Tools may allow 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 · high confidenceInteger overflow vulnerability in Intel Aptio V UEFI Firmware Integrator Tools allows an authenticated local user to trigger a denial of service condition. The overflow likely occurs during improper integer arithmetic in the tool, causing unexpected behavior or system instability.

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 Intel Aptio V UEFI Firmware Integrator Tools installationLocate the tool on the system. Common paths include C:\Program Files\Intel\Aptio V Firmware Integrator or /opt/intel/aptio. Check program files directories or use file system search for 'AptioV Firmware Integrator.exe' or similar executable names.Affected if The tool is installed on the system
-
Determine installed versionRight-click the Firmware Integrator executable, select Properties, and view the File Version field in the Details tab. Alternatively, run the executable with /? or -v flag if supported, or check Windows Registry under HKLM\SOFTWARE\Intel\AptioV for version entries.Affected if Version equals exactly 5.27.03.0003 or 5.27.06.0017
-
Verify local user access to the toolCheck file system permissions on the tool's directory and executable. Use icacls (Windows) or ls -la (Linux) to list which users or groups have Execute permission.Affected if Non-administrative local users have execute permission on the tool
-
Confirm tool execution capabilityAttempt to run the tool or check if it can be invoked by a low-privilege authenticated user. On Windows, use whoami /all to verify current user context and permissions.Affected if Authenticated local user can execute the Firmware Integrator tool
A system is affected if Intel Aptio V UEFI Firmware Integrator Tools version 5.27.03.0003 or 5.27.06.0017 is installed and local authenticated users can execute the tool.
