Unpatchable supply-chain zero-day claimed in PyTorch autograd: weights as RAM, SGD as CPU
cephaloform · x · 2026-10-22
An X post alleges an (unpatchable?) supply-chain zero-day in PyTorch autograd that lets a regularization term use the model's weights as RAM and SGD as its CPU clock to run arbitrary computation during training. Shared jokingly as "Happy Unsecurity Day"; no official response or full details yet.
