CVE-2023-27305
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 Intel(R) Arc(TM) Control software before version 1.73.5335.2 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 confidenceIntel Arc Control software before version 1.73.5335.2 contains incorrect default permissions that allow an authenticated local user to escalate privileges. This is a local privilege escalation vulnerability requiring the attacker to have valid credentials for the system.

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.
-
Verify Intel Arc Control is installedOpen Windows Settings > Apps > Installed apps, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object {$_.DisplayName -like "*Intel*Arc*Control*"}' in PowerShell to search the registry for Intel Arc Control.Affected if Intel Arc Control appears in installed programs or registry entries.
-
Determine installed Intel Arc Control versionRight-click the Intel Arc Control application in the system tray or Start menu, select 'About' or 'Help' > 'About Intel Arc Control' to view the version number. Alternatively, check the file version of 'IntelArcControl.exe' in the installation directory (typically in Program Files or Program Files (x86)).Affected if The displayed version is below 31.0.101.4255.
-
Confirm graphics hardware is affectedOpen Device Manager > Display adapters to identify the installed Intel GPU model. Alternatively, run 'Get-WmiObject Win32_VideoController' in PowerShell to retrieve the graphics device name.Affected if The system uses an Intel Iris Xe Graphics or Intel Arc A Graphics GPU.
-
Check for vulnerable service permissions (optional verification)Run 'sc qc ArcControlService' (or the actual service name for Intel Arc Control) to inspect the service configuration, then use 'icacls' on the executable path to verify file permissions align with vendor documentation.Affected if Non-privileged users have write or modify access to the Intel Arc Control executable or service binary.
A system is affected if Intel Arc Control is installed with a version prior to 31.0.101.4255 on a machine equipped with Intel Iris Xe Graphics or Intel Arc A Graphics hardware.
