CVE-2023-23909
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 · uneditedOut-of-bounds read for some Intel(R) Trace Analyzer and Collector software before version 2021.8.0 published Dec 2022 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.
dbcve analysis · high confidenceOut-of-bounds read vulnerability in Intel Trace Analyzer and Collector versions before 2021.8.0 allows an authenticated user with local access to potentially read sensitive information from memory beyond allocated buffers, leading to information disclosure.

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.
-
Check Intel Trace Analyzer and Collector versionRun 'source /opt/intel/oneapi/setvars.sh 2>/dev/null; itt --version 2>/dev/null' or check /opt/intel/oneapi/vtune/../version.txt for the Trace Analyzer component, or list installed packages with 'dpkg -l | grep -i itac' or 'rpm -qa | grep -i itac'Affected if Version is present but below 2021.8.0
-
Check Intel OneAPI HPC Toolkit versionRun 'source /opt/intel/oneapi/setvars.sh 2>/dev/null; cat /opt/intel/oneapi/intel_product_version.xml 2>/dev/null | grep -i hpc' or check the installer log in /var/log/intel.oneapi.* for the HPC Toolkit versionAffected if Version is present but below 2023.0.0
-
Verify the vulnerable component is actually installed and accessibleCheck for the itac (Intel Trace Analyzer and Collector) binaries in /opt/intel/oneapi/ by running 'find /opt/intel -name "itac*" -type f 2>/dev/null' or checking if 'itt' command is available after sourcing setvars.shAffected if The itac/itt component exists in the installation
The environment is affected if Intel Trace Analyzer and Collector below version 2021.8.0 OR Intel OneAPI HPC Toolkit below version 2023.0.0 is installed and the itac/itt component is present.

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 · scoped2021.8.02023.0.0
