CRITICAL 9.8REMOTEMITIGATE

CVE-2025-65213 is a critical-severity flaw (CVSS 9.8) affecting torch musa. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

MooreThreads torch_musa through all versions contains an unsafe deserialization vulnerability in torch_musa.utils.compare_tool. The compare_for_single_op() and nan_inf_track_for_single_op() functions use pickle.load() on user-controlled file paths without validation, allowing arbitrary code execution. An attacker can craft a malicious pickle file that executes arbitrary Python code when loaded, enabling remote code execution with the privileges o
