CVE-2025-23247: 
Linux Debian vulnerability analysis and mitigation

NVIDIA CUDA Toolkit contains a vulnerability (CVE-2025-23247) in the cuobjdump binary, discovered in May 2025. The vulnerability stems from a failure to check the length of a buffer when processing malformed ELF files. This affects all platforms running CUDA Toolkit versions up to 12.9 (NVIDIA Bulletin, NVD).

The vulnerability is classified as CWE-130 (Improper Handling of Length Parameter Inconsistency) with a CVSS v3.1 base score of 4.4 (Medium). The technical root cause involves an integer overflow vulnerability in the ELF Section Parsing functionality of NVIDIA cuobjdump. The issue occurs during the parsing of .nvdebugsource sections, where a 2-byte value from the input can trigger an integer overflow, leading to a buffer underwrite condition (Talos Report).

A successful exploitation of this vulnerability could allow an attacker to cause the tool to crash or execute arbitrary code by passing in a malformed ELF file. The vulnerability affects the confidentiality and integrity of the system with low impact, while having no direct impact on availability (NVIDIA Bulletin).

NVIDIA has released a security update addressing this vulnerability in CUDA Toolkit version 12.9. Users are strongly advised to upgrade to this latest version to protect their systems. The update is available through the CUDA Toolkit Downloads page (NVIDIA Bulletin).
