Technical details

The vulnerability exists in the checkpoint loading mechanism of Megatron-LM, where deserialization of malicious checkpoint files can lead to arbitrary code execution. An attacker must convince a user to load a crafted file, making this a user-interaction attack vector. A successful exploit grants full code execution and privilege escalation capabilities.
