NVIDIA Megatron Bridge for Linux contains a vulnerability where an attacker could cause deserialization of untrusted data. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, and information disclosure.
Articles & Coverage 1
AnalysisAI
Arbitrary code execution in NVIDIA Megatron Bridge for Linux arises from unsafe deserialization of untrusted data (CWE-502), allowing an attacker who tricks a user into loading a crafted serialized object to execute code, escalate privileges, tamper with data, and disclose information. The flaw affects the Megatron Bridge model-conversion/training tooling and is locally exploitable but hinges on victim interaction (UI:R). …
