CVE-2022-23592Network attack vector

Memory disclosure or crash via unchecked type index

Published Feb 4, 2022 · Updated Apr 22, 2025

Heap out-of-bounds read in TensorFlow 2.8.0-rc0 allows remote authenticated users to read process memory or crash a service via crafted graph metadata. RunForwardTypeInference trusts input_idx after enforcing its upper bound only with DCHECK, which is disabled in production, and then reads node_t.args(ix). Reachability requires an application to process attacker-controlled graph metadata; an invalid index can expose adjacent heap data or terminate the hosting process.
