CVE-2022-26841
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 · uneditedInsufficient control flow management for the Intel(R) SGX SDK software for Linux before version 2.16.100.1 may allow an authenticated user to potentially enable information disclosure 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.
-
Verify Intel SGX SDK installationLocate the Intel SGX SDK installation directory on the system. Common locations include /opt/intel/sgxsdk or /usr/local/sgxsdk. Check for the presence of SDK components such as the sdkml or libsgx_*.so files.Affected if Intel SGX SDK for Linux is installed on the system
-
Determine installed SDK versionRun 'sgx_sdk_version' if available, or inspect the version file within the SDK installation directory (typically found in a version info file or the SDK's Makefile). Compare the version string against the affected ranges.Affected if The installed version is lower than 2.16.100.1 (or lower than 2.15.100.1 if using that branch)
-
Confirm local user access exposureVerify that local unprivileged or authenticated user accounts exist on the system and can access the SGX SDK tooling or its runtime components.Affected if Local authenticated user accounts exist and can interact with the SGX SDK environment
The environment is affected if Intel SGX SDK for Linux is installed with a version below 2.16.100.1 and local user access to the system is possible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.15.100.12.16.100.1
Upgrade Intel SGX SDK for Linux to version 2.16.100.1 or later to remediate this vulnerability.
Intel SGX SDK for Linux version 2.16.100.1 (or 2.15.100.1 for the 2.15.x branch)
- Identify the currently installed Intel SGX SDK version using 'sgx_sdk --version' or checking the installed packages
- Download Intel SGX SDK version 2.16.100.1 (or 2.15.100.1 for the 2.15.x branch) from the official Intel website or Intel Repository
- Backup any existing enclave projects and configuration files before upgrading
- Uninstall the current SGX SDK version following Intel's uninstallation documentation
- Install the new SGX SDK version 2.16.100.1 using the provided installer (typically './install.sh' with appropriate permissions)
- Rebuild any existing enclave projects with the new SDK to ensure compatibility
- Verify the installed version matches the target fixed version
