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.

Affected products
