CVE-2025-55556Public exploitNetwork attack vector

Silent incorrectness via XLA-compiled Embedding

Published Sep 25, 2025 · Updated Sep 25, 2025

Incorrect calculation in TensorFlow 2.18.0 allows remote attackers to corrupt model output via an XLA-compiled Embedding layer. With input_dim set to 1 and an out-of-range index of 1, the JIT-compiled path returns a random tensor instead of the zero produced without XLA. Exploitation requires an application to accept an attacker-selected model or index and enable XLA JIT compilation; the corrupted output can silently drive incorrect decisions.
