{"cve":"CVE-2021-41216","nvd":{"published":"2021-11-05T23:15:08.287","modified":"2026-06-17T04:08:06.843","status":"Modified","description":"TensorFlow is an open source platform for machine learning. In affected versions the shape inference function for `Transpose` is vulnerable to a heap buffer overflow. This occurs whenever `perm` contains negative elements. The shape inference function does not validate that the indices in `perm` are all valid. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-787","CWE-120"],"references":["https://github.com/tensorflow/tensorflow/commit/c79ba87153ee343401dbe9d1954d7f79e521eb14","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-3ff2-r28g-w7h9","https://github.com/tensorflow/tensorflow/commit/c79ba87153ee343401dbe9d1954d7f79e521eb14","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-3ff2-r28g-w7h9"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:24:39.218183596+00:00"},"epss":{"cve":"CVE-2021-41216","score":0.00161,"percentile":0.05316,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3ff2-r28g-w7h9","url":"https://osv.dev/vulnerability/GHSA-3ff2-r28g-w7h9","summary":"Heap buffer overflow in `Transpose`","modified":"2026-07-08T06:28:09.424674617Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.6.0 <2.6.1"],"fixed":["2.6.1"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.5.0 <2.5.2"],"fixed":["2.5.2"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.4.4"],"fixed":["2.4.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.6.0 <2.6.1"],"fixed":["2.6.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.5.0 <2.5.2"],"fixed":["2.5.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.4.4"],"fixed":["2.4.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.6.0 <2.6.1"],"fixed":["2.6.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.5.0 <2.5.2"],"fixed":["2.5.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.4.4"],"fixed":["2.4.4"]}]},{"id":"PYSEC-2021-408","url":"https://osv.dev/vulnerability/PYSEC-2021-408","summary":"","modified":"2023-12-06T01:01:34.709824Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.4.4",">=2.5.0 <2.5.2",">=2.6.0 <2.6.1",">=2.7.0rc0 <2.7.0"],"fixed":["2.4.4","2.5.2","2.6.1","2.7.0"]}]},{"id":"PYSEC-2021-625","url":"https://osv.dev/vulnerability/PYSEC-2021-625","summary":"","modified":"2023-12-06T01:01:34.709824Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.4.4",">=2.5.0 <2.5.2",">=2.6.0 <2.6.1",">=2.7.0rc0 <2.7.0"],"fixed":["2.4.4","2.5.2","2.6.1","2.7.0"]}]},{"id":"PYSEC-2021-823","url":"https://osv.dev/vulnerability/PYSEC-2021-823","summary":"","modified":"2023-12-06T01:01:34.709824Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.4.4",">=2.5.0 <2.5.2",">=2.6.0 <2.6.1",">=2.7.0rc0 <2.7.0"],"fixed":["2.4.4","2.5.2","2.6.1","2.7.0"]}]}],"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).
