Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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 of the victim process.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

MooreThreads torch_musa library contains an unsafe deserialization vulnerability in torch_musa.utils.compare_tool. The compare_for_single_op() and nan_inf_track_for_single_op() functions directly use pickle.load() on user-controlled file paths without any validation, allowing attackers to craft malicious pickle files that execute arbitrary Python code when loaded by the victim process.

MitigationReplace pickle.load() with safe deserialization methods (e.g., JSON) or implement strict input validation and path sanitization before loading any file. If pickle must be used, employ RestrictedUnpickler with a whitelist of allowed classes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check if torch_musa is installed
    Run 'pip show torch_musa' or 'python -c "import torch_musa; print(torch_musa.__file__)"' to confirm the library is present in your environment
    Affected if torch_musa is installed and importable - the library is present in the environment
  2. Verify the compare_tool module exists
    Run 'python -c "from torch_musa.utils import compare_tool; print(compare_tool.__file__)"' to confirm the vulnerable module is available
    Affected if The compare_tool module exists and can be imported - the vulnerable code path is accessible
  3. Check for usage of vulnerable functions
    Search codebase for calls to compare_for_single_op() or nan_inf_track_for_single_op() from torch_musa.utils.compare_tool, or inspect the source directly if accessible
    Affected if Code directly calls these functions with user-controlled file paths, or the module is imported and used in any application that processes external files
  4. Confirm application processes external pickle files
    Audit any code paths that invoke these functions to determine if they accept file paths from users, external sources, or untrusted input
    Affected if External or user-supplied file paths are passed to these functions without validation, enabling exploitation

If torch_musa is installed and its compare_tool module processes untrusted file paths through pickle.load(), the environment is vulnerable to arbitrary code execution via malicious pickle deserialization.

Mitigation

Replace pickle.load() with safe deserialization methods (e.g., JSON) or implement strict input validation and path sanitization before loading any file. If pickle must be used, employ RestrictedUnpickler with a whitelist of allowed classes.
