{"cve":"CVE-2022-29200","nvd":{"published":"2022-05-20T22:16:40.933","modified":"2026-06-17T04:39:48.310","status":"Modified","description":"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.LSTMBlockCell` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. The code does not validate the ranks of any of the arguments to this API call. This results in `CHECK`-failures when the elements of the tensor are accessed. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-1284","CWE-20"],"references":["https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/rnn/lstm_ops.cc","https://github.com/tensorflow/tensorflow/commit/803404044ae7a1efac48ba82d74111fce1ddb09a","https://github.com/tensorflow/tensorflow/releases/tag/v2.6.4","https://github.com/tensorflow/tensorflow/releases/tag/v2.7.2","https://github.com/tensorflow/tensorflow/releases/tag/v2.8.1"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29200","score":0.00325,"percentile":0.25601,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2vv3-56qg-g2cf","url":"https://osv.dev/vulnerability/GHSA-2vv3-56qg-g2cf","summary":"Missing validation causes denial of service via `LSTMBlockCell`","modified":"2026-07-13T16:43:00.481122463Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.6.4"],"fixed":["2.6.4"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.7.0 <2.7.2"],"fixed":["2.7.2"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.8.0 <2.8.1"],"fixed":["2.8.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.6.4"],"fixed":["2.6.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.7.0 <2.7.2"],"fixed":["2.7.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.8.0 <2.8.1"],"fixed":["2.8.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.6.4"],"fixed":["2.6.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.7.0 <2.7.2"],"fixed":["2.7.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.8.0 <2.8.1"],"fixed":["2.8.1"]}]},{"id":"PYSEC-2026-3089","url":"https://osv.dev/vulnerability/PYSEC-2026-3089","summary":"Missing validation causes denial of service via `LSTMBlockCell`","modified":"2026-07-13T16:43:00.481122463Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.6.4",">=2.7.0 <2.7.2",">=2.8.0 <2.8.1"],"fixed":["2.6.4","2.7.2","2.8.1"]}]},{"id":"PYSEC-2026-3267","url":"https://osv.dev/vulnerability/PYSEC-2026-3267","summary":"Missing validation causes denial of service via `LSTMBlockCell`","modified":"2026-07-13T16:43:00.481122463Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.6.4",">=2.7.0 <2.7.2",">=2.8.0 <2.8.1"],"fixed":["2.6.4","2.7.2","2.8.1"]}]},{"id":"PYSEC-2026-944","url":"https://osv.dev/vulnerability/PYSEC-2026-944","summary":"Missing validation causes denial of service via `LSTMBlockCell`","modified":"2026-07-13T16:43:00.481122463Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.6.4",">=2.7.0 <2.7.2",">=2.8.0 <2.8.1"],"fixed":["2.6.4","2.7.2","2.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
