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
Uncontrolled search path in some Intel(R) RST software before versions 16.8.5.1014.5, 17.11.3.1010.2, 18.7.6.1011.2 and 19.5.2.1049.5 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 confidence

Intel Rapid Storage Technology (RST) software contains an uncontrolled search path vulnerability where the application may load executable files from locations controlled by an authenticated local user. This allows privilege escalation from a standard user to higher privileges by placing a malicious executable in a searched path.

MitigationUpdate Intel RST software to version 16.8.5.1014.5 or later for version 16.x, 17.11.3.1010.2 or later for version 17.x, 18.7.6.1011.2 or later for version 18.x, or 19.5.2.1049.5 or later for version 19.x.

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 RST is installed
    Open Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product' in PowerShell, and look for entries containing 'Intel Rapid Storage Technology' or similar.
    Affected if Intel Rapid Storage Technology appears in the installed programs list.
  2. Find the installed version of Intel RST
    In Programs and Features, click on the Intel Rapid Storage Technology entry to view the version. Alternatively, check the file properties of the main executable (typically in C:\Program Files\Intel\Intel(R) Rapid Storage Technology\ or C:\Program Files (x86)\Intel\Intel(R) Rapid Storage Technology\) by right-clicking 'IAStorUI.exe' or similar and selecting Properties > Details.
    Affected if A version number is displayed.
  3. Compare against affected version ranges
    Note the full version number (for example, 16.8.5.1014) and compare it numerically to the vulnerable ranges: 16.0 through 16.8.5.1013.x, 17.0 through 17.11.3.1010.1, 18.0 through 18.7.6.1011.1, or 19.0 through 19.5.2.1049.4.
    Affected if The installed version falls within any of these ranges: >= 16.0 and < 16.8.5.1014.5; >= 17.0 and < 17.11.3.1010.2; >= 18.0 and < 18.7.6.1011.2; or >= 19.0 and < 19.5.2.1049.5.
  4. Check if the application runs with elevated privileges
    Observe whether the Intel RST application or its service runs under a privileged account (such as SYSTEM or an administrator-level account) rather than a standard user account.
    Affected if The application runs with elevated privileges and a standard user can place files in directories that the application searches.

The system is affected if Intel Rapid Storage Technology is installed and its version falls within any of the vulnerable version ranges (16.0 to < 16.8.5.1014.5, 17.0 to < 17.11.3.1010.2, 18.0 to < 18.7.6.1011.2, or 19.0 to < 19.5.2.1049.5).

Fixed in 16.8.5.1014.517.11.3.1010.218.7.6.1011.2
Interim mitigation

Update Intel RST software to version 16.8.5.1014.5 or later for version 16.x, 17.11.3.1010.2 or later for version 17.x, 18.7.6.1011.2 or later for version 18.x, or 19.5.2.1049.5 or later for version 19.x.

Recommended fix High confidence

Upgrade to version 16.8.5.1014.5 (for 16.x), 17.11.3.1010.2 (for 17.x), 18.7.6.1011.2 (for 18.x), or 19.5.2.1049.5 (for 19.x)

  1. Identify the currently installed Intel Rapid Storage Technology version via Programs and Features or Intel RST interface
  2. Download the appropriate fixed version from Intel's support website (www.intel.com) based on your current major version (16.x, 17.x, 18.x, or 19.x)
  3. Close any applications that may be using Intel RST prior to installation
  4. Run the Intel RST installer with administrator privileges
  5. Follow the on-screen installation prompts to complete the upgrade
  6. Restart the system when prompted to ensure the driver update takes effect
  7. Verify the installed version matches the target fixed version (16.8.5.1014.5, 17.11.3.1010.2, 18.7.6.1011.2, or 19.5.2.1049.5)
Caveat Driver updates may temporarily disrupt storage controller functionality; ensure backups exist before upgrading
