CVE-2025-46153 (opens in a new tab)How to fix?
Upgrade torch to version 2.7.0 or higher.
Overview
torch is a Tensors and Dynamic neural networks in Python with strong GPU acceleration
Affected versions of this package are vulnerable to Inefficient CPU Computation due to inconsistent behavior in the bernoulli_p() function when used in RNG nn.Dropout1d, nn.Dropout2d, and nn.Dropout3d. An attacker can cause unintended or incorrect dropout behavior in neural network layers by triggering fallback to the affected implementation when fallback_random=True.
