Technical details
The vulnerability is a classic unsafe deserialization flaw in NVIDIA Megatron Bridge where untrusted data is deserialized without proper validation. This allows an attacker to inject malicious serialized objects that execute arbitrary code upon deserialization. The attack vector depends on how Megatron Bridge receives and processes serialized data—typically this would require network access to the service or the ability to influence data being processed. A successful exploit grants the attacker code execution privileges equivalent to the process running Megatron Bridge, enabling data tampering and information disclosure.
