CVE-2025-55552Public exploitNetwork attack vector

Silent output corruption via inconsistent Inductor compilation

Published Sep 25, 2025 · Updated Sep 25, 2025

Incorrect calculation in PyTorch 2.8.0 and earlier allows remote attackers to corrupt model output via an Inductor-compiled model. The Inductor-compiled path generates random tensor elements in a different order than eager execution when torch.randn_like follows torch.rot90. Reachability requires an application to compile attacker-supplied model logic containing both operations; the demonstrated consequence is silent output corruption rather than a crash.
