CVE-2022-29193: TensorFlow: DoS via TensorSummaryV2 input validation failure

MEDIUM PoC AVAILABLE CISA: TRACK*
Published May 20, 2022
CISO Take

A low-privilege local user can crash TensorFlow processes by passing invalid arguments to tf.raw_ops.TensorSummaryV2, triggering a CHECK-failure. Patch to TF 2.9.0, 2.8.1, 2.7.2, or 2.6.4 immediately — multi-tenant ML environments (shared Jupyter clusters, CI/CD training pipelines) are the primary risk surface. Impact is availability only; no data exfiltration or code execution.

What is the risk?

Effective risk is LOW-MEDIUM despite CVSS 5.5. The local attack vector significantly limits exposure — an attacker needs an authenticated session on the host running TensorFlow. In dedicated single-user workstations the risk is negligible. In shared ML platforms (JupyterHub, Kubeflow, SageMaker Studio multi-tenant), a malicious or compromised tenant could disrupt co-located training jobs. The vulnerability requires no AI/ML expertise and is trivially exploitable once local access is obtained. Not in CISA KEV; no evidence of in-the-wild exploitation.

What should I do?

5 steps
  1. PATCH

    Upgrade TensorFlow to 2.9.0, 2.8.1, 2.7.2, or 2.6.4. Verify with pip show tensorflow.

  2. WORKAROUND

    Audit code for direct calls to tf.raw_ops.TensorSummaryV2 and validate tensor_dtype and metadata arguments before invocation.

  3. MULTI-TENANT HARDENING: Enforce namespace/pod isolation in Kubeflow/JupyterHub to prevent cross-tenant disruption. Apply resource quotas to limit blast radius.

  4. DETECTION

    Monitor for unexpected TensorFlow process crashes (exit code 134 / SIGABRT) in training infrastructure logs. Alert on repeated abort signals from the same user session.

  5. INVENTORY

    Identify all ML training pipelines using TensorFlow < 2.6.4 via SBOM or dependency scanning (pip-audit, Safety).

What are the technical details?

Original Advisory

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of `tf.raw_ops.TensorSummaryV2` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.

Exploitation Scenario

An insider threat or compromised data-scientist account with shell access to a shared ML training cluster imports TensorFlow and calls tf.raw_ops.TensorSummaryV2 with a malformed metadata argument (e.g., an empty or mismatched dtype). TensorFlow's CHECK macro fires, raising SIGABRT and killing the process. On a Kubernetes-based ML platform without proper pod isolation, this can be repeated in a loop to continuously abort legitimate training jobs belonging to other tenants, effectively conducting a targeted denial-of-service against specific model development efforts — without any elevated privileges.

Weaknesses (CWE)

CWE-20 — Improper Input Validation: The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

  • [Architecture and Design] Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build "recognizers" for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses. [REF-1109] [REF-1110] [REF-1111]
  • [Architecture and Design] Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
