Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The PyTorch torch package before 2.10.0 has a flaw in its weights_only unpickler, which fails to properly validate pickle opcodes and storage metadata. An attacker who can get a user to load a crafted checkpoint file (.pth) with torch.load(..., weights_only=True) may corrupt memory and potentially execute arbitrary code in the victim's process. Upgrade torch to version 2.10.0 or later.
