Technical details
The vulnerability is a deserialization flaw in NVIDIA Megatron Bridge that allows an attacker to supply untrusted serialized data. Without proper validation before deserialization, an attacker can exploit this to achieve remote code execution, data tampering, and information disclosure. The attack vector and authentication requirements are not explicitly detailed in the advisory, but deserialization vulnerabilities typically require the ability to send or control input to the vulnerable deserialization function. No patch status is indicated in the provided information.
