CVE-2023-25670Network attack vector

Denial of service via unchecked tensor ranks

Published Mar 24, 2023 · Updated Feb 19, 2025

NULL pointer dereference in TensorFlow before 2.11.1 allows remote attackers to crash an MKL-enabled process via malformed range tensors. The MKL QuantizedMatMulWithBiasAndDequantize kernel reads the first element of min/max range tensors without first requiring scalar rank, so empty tensors trigger an invalid access. Reachability requires an application to pass attacker-controlled tensors to the MKL-enabled operation; exploitation terminates the hosting process without reported data disclosure or modification.
