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 element in the Intel(R) oneAPI Collective Communications Library (oneCCL) before version 2021.6 for Intel(R) oneAPI Base Toolkit 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 · moderate confidence

This is an uncontrolled search path element vulnerability (DLL/library hijacking) in Intel oneAPI Collective Communications Library (oneCCL) before version 2021.6. The application uses an insecure library search path, allowing an authenticated local user to place malicious libraries in a location where oneCCL will load them during execution, potentially achieving privilege escalation.

MitigationUpgrade Intel oneCCL to version 2021.6 or later within the Intel oneAPI Base Toolkit. Ensure the upgraded library paths are secured and that no untrusted locations are added to the search path.

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. Locate Intel oneCCL installation
    Search for the oneCCL installation directory - typically found under Intel oneAPI installation path (e.g., C:\Program Files (x86)\Intel\oneAPI\ or /opt/intel/oneapi/) and look for a 'ccl' or 'oneccl' folder. On Windows, also check for environment variable INTEL_ONEAPI_ROOT or OML_SDK_ROOT.
    Affected if oneCCL is not installed or the installation directory cannot be found, the system is likely not affected.
  2. Determine installed oneCCL version
    Within the oneCCL installation directory, look for a version file, README, or check the DLL/properties. On Windows, right-click ccl.dll or similar library file and view Properties > Details for version info. On Linux, check the VERSION file or library symlinks in the ccl directory.
    Affected if The installed version is less than 2021.6, the system is affected by this vulnerability.
  3. Examine library search path configuration
    Check for environment variables that control library loading: PATH (Windows) or LD_LIBRARY_PATH (Linux). Also examine any configuration files or scripts that set these paths for oneCCL execution.
    Affected if The oneCCL library path includes directories writable by untrusted users (e.g., temp directories, user home directories, network shares), the vulnerability is exploitable.
  4. Inspect for pre-existing malicious libraries
    In the directories that appear in oneCCL's search path, look for unexpected DLL/SO files with suspicious names or recent modification dates, particularly in locations writable by non-admin users.
    Affected if Unexpected or recently modified libraries are found in the search path directories, this may indicate attempted exploitation.

The system is affected if Intel oneCCL is installed with a version prior to 2021.6 and the library search path includes directories writable by untrusted users, allowing potential DLL hijacking.

dbcve · scoped
Upgrade available Upgrade to 2021.6 or later
Fixed in 2021.6
Interim mitigation

Upgrade Intel oneCCL to version 2021.6 or later within the Intel oneAPI Base Toolkit. Ensure the upgraded library paths are secured and that no untrusted locations are added to the search path.

Recommended fix High confidence

2021.6

  1. 1. Identify the currently installed version of Intel oneAPI Collective Communications Library (oneCCL) on the system
  2. 2. Download Intel oneCCL version 2021.6 or later from Intel's official website or package repository
  3. 3. Uninstall the vulnerable version of oneCCL (< 2021.6)
  4. 4. Install the fixed version (2021.6 or later) following Intel's installation instructions
  5. 5. Verify the installed version matches or exceeds 2021.6
