CVE-2022-29210

Service interruption via TensorKey heap buffer over-read

Published May 20, 2022 · Updated Apr 23, 2025

Heap buffer over-read in Google TensorFlow 2.8.0 allows local users to interrupt a process through TensorKey hashing. AbslHashValue in tensorflow/core/framework/tensor_key.h reads tensor.data() for AllocatedBytes(), although that estimate includes noncontiguous pointed-to storage. Reachability requires local code that causes an affected TensorKey to hash such a tensor; the bounded consequence is process failure rather than data disclosure or modification.
