Detailsinfo

A vulnerability was found in NVIDIA CUDA Toolkit (version now known). It has been rated as critical. This issue affects some unknown processing of the component ELF File Handler. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

NVIDIA CUDA Toolkit for all platforms contains a vulnerability in nvdisasm where an attacker may cause a heap-based buffer overflow by getting the user to run nvdisasm on a malicious ELF file. A successful exploit of this vulnerability may lead to arbitrary code execution at the privilege level of the user running nvdisasm.

The identification of this vulnerability is CVE-2025-23308 since 01/14/2025. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 266128 (Linux Distros Unpatched Vulnerability : CVE-2025-23308), which helps to determine the existence of the flaw in a target environment.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (266128) and EUVD (EUVD-2025-30963). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
