PyTorch is a Python package that provides tensor computation with strong GPU acceleration and deep neural networks built on a tape-based autograd system. In version 2.5.1 and prior, a Remote Command Execution (RCE) vulnerability exists in PyTorch when loading a model using torch.load with weights_only=True. This issue has been patched in version 2.6.0.

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dla-4389 advisory.

    A possible remote code execution (RCE) vulnerability has been     discovered in pytorch, an open source machine learning framework.


    CVE-2025-32434

       Possible RCE when loading a model using torch.load with        weights_only=True.


    For Debian 11 bullseye, this problem has been fixed in version     1.7.1-7+deb11u1.

    We recommend that you upgrade your pytorch packages.
