CVE-2022-21737Public exploitNetwork attack vector

Process crash via non-scalar Bincount size

Published Feb 3, 2022 · Updated May 5, 2025

Denial of service in TensorFlow allows remote authenticated users to crash a serving process by submitting malformed Bincount inputs. Dense, Sparse, and Ragged Bincount paths treat the size tensor as a scalar without first rejecting a non-scalar rank, causing a CHECK failure during later output allocation. Exploitation requires control of tensors supplied to an exposed TensorFlow workload; the demonstrated consequence is process termination without data disclosure or modification.
