CVE-2025-55554Public exploitNetwork attack vector

Incorrect tensor results via Inductor integer overflow

Published Sep 25, 2025 · Updated Sep 25, 2025

Integer overflow in PyTorch 2.8.0 and earlier allows remote attackers to produce incorrect tensor results through compiled models. CPU Inductor mishandles positive infinity processed by torch.nan_to_num before a long conversion, producing the opposite signed 64-bit boundary value from eager execution. The flaw requires CPU Inductor compilation of that operation sequence and an infinite input; the bounded consequence is silent calculation corruption.
