Detailsinfo

A vulnerability, which was classified as critical, was found in NVIDIA Nsight Systems (version unknown). This affects the function gfx_hotspot of the file process_nsys_rep_cli.py. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

NVIDIA Nsight Systems contains a vulnerability in the gfx_hotspot recipe, where an attacker could cause an OS command injection by supplying a malicious string to the process_nsys_rep_cli.py script if the script is invoked manually. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure.

This vulnerability is uniquely identified as CVE-2025-33228. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/27/2026).
