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 · uneditedImproper access control in the Crypto API Toolkit for Intel(R) SGX before version 2.0 commit ID 91ee496 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.

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 if Intel Crypto API Toolkit for Intel SGX is installedCheck the installed software or available packages for 'Intel Crypto API Toolkit' or 'Intel SGX Crypto' components. Look in installed programs, package managers, or the Intel SGX SDK/Platform Software directory.Affected if The software is present on the system
-
Determine the installed version of Intel Crypto API ToolkitLocate the version information for the installed Intel Crypto API Toolkit. Check the toolkit's manifest, version file, or run 'version' commands if available. The toolkit may be bundled with the Intel SGX SDK or Platform Software.Affected if The version is less than 2.0 or the commit ID is earlier than 91ee496
-
Verify if the Crypto API Toolkit components are in useCheck if the Crypto API Toolkit service, driver, or enclave application is active. Look for sgx_enclave processes, crypto API modules, or related services.Affected if The toolkit components are actively loaded or running
A system is affected if Intel Crypto API Toolkit for Intel SGX is installed with a version prior to 2.0 (or commit ID earlier than 91ee496) and the toolkit components are enabled or in use.
