Executive brief
NVIDIA Megatron Bridge, a tool used for bridging large-scale machine learning models, contains a security flaw in how it processes data. An attacker could exploit this by tricking a user into opening a malicious file, potentially allowing the attacker to take control of the system, steal sensitive information, or modify data. This could lead to a full compromise of the workstation or server where the software is running.
Technical details
NVIDIA Megatron Bridge for Linux (versions 0.0 through 0.4.0) is vulnerable to CWE-502 (Deserialization of Untrusted Data). The vulnerability exists because the application fails to properly validate or sanitize data before deserializing it, which can be exploited if a local user is enticed into processing a specially crafted malicious file (User Interaction required). A successful exploit allows an attacker to execute arbitrary code with the privileges of the application, potentially leading to full system compromise, unauthorized data access, and escalation of privileges. The CVSS 3.1 vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.
