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 · unedited
Improper access control for some Intel Vision software for all versions within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable remote code execution. This result may potentially occur via network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

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 confidence

Improper access control vulnerability in Intel Vision software user-mode applications (Ring 3) allows an unprivileged, unauthenticated attacker with network access to potentially execute remote code or cause denial of service. The vulnerability stems from insufficient access control checks in the user-space component.

MitigationApply Intel-provided patches for Intel Vision software; until patched, restrict network access to affected systems and minimize the attack surface by removing unnecessary Intel Vision installations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Intel Vision software is installed
    Check for Intel Vision installation directories (commonly in C:\Program Files\Intel\Vision or /opt/intel/vision) and look for vision-related executables or services using 'Get-WmiObject Win32_Product' or reviewing installed programs in Control Panel
    Affected if Intel Vision software is present on the system
  2. Identify installed Intel Vision version
    Query the installed version from the executable or installed package. Look for version info in the software's main executable or check registry keys under HKLM\SOFTWARE\Intel\Vision if present
    Affected if The installed version matches or precedes the patched version released by Intel for this CVE
  3. Check network exposure of Intel Vision services
    Use 'netstat -an' or 'Get-NetTCPConnection' to identify ports where Intel Vision components are listening. Review any exposed network services in the software configuration
    Affected if Intel Vision user-mode services are bound to network interfaces and accessible remotely
  4. Verify service configuration and privileges
    Review Intel Vision service settings via 'services.msc' or 'sc query' to confirm the user context (should not be running with excessive privileges)
    Affected if The service runs with elevated privileges or has misconfigured access controls
  5. Inspect application logs for access control anomalies
    Review Intel Vision application logs (typically in the software's log directory) for failed access control checks or unusual authentication events
    Affected if Logs indicate bypassed or failed access control checks consistent with this vulnerability

The system is affected if Intel Vision software is installed, running a vulnerable version, and exposed to network access where an unauthenticated attacker could exploit the insufficient access control checks in the user-mode component.
