CVE-2022-23564Network attack vector

Process crash via oversized protobuf tensor shape

Published Feb 4, 2022 · Updated Apr 23, 2025

Reachable assertion in Google TensorFlow before 2.5.3, 2.6.0 through 2.6.2, and 2.7.0 allows remote authenticated users to crash processes. ResourceHandle::FromProto directly constructs partial tensor shapes from protobuf data, so an oversized element count invalidates a CHECK assertion. A caller must supply a crafted resource-handle TensorProto to a TensorFlow process; the resulting exit interrupts that process without reported data exposure.
