{"cve":"CVE-2022-29208","nvd":{"published":"2022-05-20T23:15:45.150","modified":"2026-06-17T04:39:49.590","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.EditDistance` has incomplete validation. Users can pass negative values to cause a segmentation fault based denial of service. In multiple places throughout the code, one may compute an index for a write operation. However, the existing validation only checks against the upper bound of the array. Hence, it is possible to write before the array by massaging the input to generate negative values for `loc`. 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:H/A:H","score":7.1},"cwes":["CWE-787"],"references":["https://github.com/tensorflow/tensorflow/commit/30721cf564cb029d34535446d6a5a6357bebc8e7","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","https://github.com/tensorflow/tensorflow/releases/tag/v2.9.0"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29208","score":0.00387,"percentile":0.32853,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2r2f-g8mw-9gvr","url":"https://osv.dev/vulnerability/GHSA-2r2f-g8mw-9gvr","summary":"Segfault and OOB write due to incomplete validation in `EditDistance` in TensorFlow","modified":"2026-07-13T16:42:40.712669136Z","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-2026-3088","url":"https://osv.dev/vulnerability/PYSEC-2026-3088","summary":"Segfault and OOB write due to incomplete validation in `EditDistance` in TensorFlow","modified":"2026-07-13T16:42:40.712669136Z","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-2026-3266","url":"https://osv.dev/vulnerability/PYSEC-2026-3266","summary":"Segfault and OOB write due to incomplete validation in `EditDistance` in TensorFlow","modified":"2026-07-13T16:42:40.712669136Z","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-2026-943","url":"https://osv.dev/vulnerability/PYSEC-2026-943","summary":"Segfault and OOB write due to incomplete validation in `EditDistance` in TensorFlow","modified":"2026-07-13T16:42:40.712669136Z","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).
