Details

This section provides a summary of potential vulnerabilities that this security update addresses and their impact. Descriptions use CWE™, and base scores and vectors use CVSS v3.1 standards.

CVE ID Description Base Score Vector
CVE‑2022‑21821 NVIDIA CUDA Toolkit SDK contains an integer overflow vulnerability in cuobjdump.To exploit this vulnerability, a remote attacker would require a local user to download a specially crafted, corrupted file and locally execute cuobjdump against the file. Such an attack may lead to remote code execution that causes complete denial of service and an impact on data confidentiality and integrity. 7.8 AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

The NVIDIA risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk to your local installation. NVIDIA recommends evaluating the risk to your specific configuration.

Notes

  • Earlier software releases that support this product are also affected. If you are using an earlier release, upgrade to the latest release version.

Mitigations

If you address this vulnerability by installing the CUDA Toolkit version listed in Security Updates, it is recommended, but not required, that you also update the CUDA driver at the same time. If you prefer to remain on an older CUDA driver, refer to CUDA Compatibility for more information.

This issue exists in the standalone developer utility cuobjdump, which is shipped with CUDA Toolkit. It does not affect normal runtime execution of CUDA. It is encountered only when developer tools are run against specifically malformed binaries.

Applications that are built with or distributed with the CUDA runtime components listed in Attachment A of the CUDA EULA are not affected by this vulnerability. The base and runtime variants of NGC CUDA containers are also unaffected because they do not contain the cuobjdump utility.

Acknowledgements

NVIDIA thanks Leonardo Galli for reporting this issue.
