AnalysisAI
Arbitrary code execution in NVIDIA Megatron Bridge (all versions per the NVIDIA advisory) arises from unsafe deserialization of untrusted data (CWE-502), where an attacker supplies a crafted serialized object — typically a malicious model checkpoint or configuration artifact — that a user loads locally, yielding code execution, privilege escalation, data tampering, and information disclosure. The CVSS 3.1 base score is 7.8 (High) with a local vector requiring user interaction (AV:L/UI:R) and no attacker privileges. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; no EPSS score was provided.
