CVE-2023-25659Public exploitNetwork attack vector

Process interruption via unchecked negative DynamicStitch index

Published Mar 24, 2023 · Updated Feb 19, 2025

Out-of-bounds read in Google TensorFlow before 2.11.1 allows remote attackers to interrupt a hosting process through crafted DynamicStitch inputs. DynamicStitch accepted a negative index and reached source-vector access or copy preparation before applying a complete bounds check. Reachability requires an application to execute attacker-controlled DynamicStitch arguments; the published impact is loss of process availability, with no confidentiality or integrity impact reported.
