Executive brief
NVIDIA Megatron Bridge, a tool used for connecting large-scale machine learning models, contains a security vulnerability in how it handles data inputs. An attacker with local access to the system could exploit this flaw to take control of the software, potentially leading to unauthorized access to sensitive data or a full system takeover. This could disrupt AI development workflows and compromise the integrity of proprietary machine learning models.
Technical details
NVIDIA Megatron Bridge for Linux (versions 0.0 through 0.4.0) is vulnerable to the deserialization of untrusted data (CWE-502). The root cause is improper validation of allowed inputs within the bridge component. An attacker with local access and low-level privileges can provide a specially crafted input that, when processed, allows for arbitrary code execution, escalation of privileges, and unauthorized data access. The vulnerability is tracked as CVE-2026-24250 and has a CVSS 3.1 base score of 7.8.
