CVE-2022-21156
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 · uneditedAccess of uninitialized pointer in the Intel(R) Trace Analyzer and Collector before version 2021.5 may allow an authenticated user to potentially enable denial of service 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 confidenceAn uninitialized pointer vulnerability in Intel(R) Trace Analyzer and Collector versions prior to 2021.5 allows an authenticated local user to trigger a denial of service by accessing the uninitialized pointer, which can cause the application to crash or become unstable.

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.
-
Confirm Intel Trace Analyzer and Collector installationSearch common installation directories (C:\Program Files\Intel\, /opt/intel/, or %LOCALAPPDATA%\Intel\) for 'itracemgr', 'itac', or 'traceanalyzer' executables. On Windows check Add/Remove Programs. On Linux check package manager (rpm -qa | grep -i itac or dpkg -l | grep -i itac).Affected if The software is installed on the system
-
Identify installed version numberRun the application with --version flag (e.g., itac --version, mpirun --version with itac attached) or check the 'About' dialog in the GUI. On Windows check the file properties of the main executable. On Linux check the version via the installer package or /opt/intel/itac/version.xml if present.Affected if Version number returned is lower than 2021.5 (for example 2021.4, 2021.3, 2020.x, etc.)
-
Verify vulnerable application binaries are presentLocate the core binaries: itac, itracemgr, libVT.dll, or libVT.so in the installation directory. These are the components that process trace files and could trigger the uninitialized pointer during normal operation.Affected if The binaries exist and are from a version prior to 2021.5
-
Confirm local user access to the applicationVerify that local users on the system can execute the Intel Trace Analyzer or Collector binaries (check file permissions and user group membership). The vulnerability is triggered by an authenticated local user.Affected if Local authenticated users have execute permissions on the vulnerable itac/itracemgr binaries
The system is affected if Intel Trace Analyzer and Collector is installed with a version number lower than 2021.5 and local users can access the application binaries.
