{"cve":"CVE-2021-41203","nvd":{"published":"2021-11-05T21:15:08.613","modified":"2026-06-17T04:08:05.300","status":"Modified","description":"TensorFlow is an open source platform for machine learning. In affected versions an attacker can trigger undefined behavior, integer overflows, segfaults and `CHECK`-fail crashes if they can change saved checkpoints from outside of TensorFlow. This is because the checkpoints loading infrastructure is missing validation for invalid file formats. The fixes will be included in TensorFlow 2.7.0. We will also cherrypick these commits 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-190","CWE-345"],"references":["https://github.com/tensorflow/tensorflow/commit/368af875869a204b4ac552b9ddda59f6a46a56ec","https://github.com/tensorflow/tensorflow/commit/abcced051cb1bd8fb05046ac3b6023a7ebcc4578","https://github.com/tensorflow/tensorflow/commit/b619c6f865715ca3b15ef1842b5b95edbaa710ad","https://github.com/tensorflow/tensorflow/commit/e8dc63704c88007ee4713076605c90188d66f3d2","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-7pxj-m4jf-r6h2"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:24:39.218183596+00:00"},"epss":{"cve":"CVE-2021-41203","score":0.00189,"percentile":0.08521,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7pxj-m4jf-r6h2","url":"https://osv.dev/vulnerability/GHSA-7pxj-m4jf-r6h2","summary":"Missing validation during checkpoint loading","modified":"2026-07-08T06:29:13.394845642Z","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-2021-396","url":"https://osv.dev/vulnerability/PYSEC-2021-396","summary":"","modified":"2023-12-06T01:01:33.927372Z","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-2021-613","url":"https://osv.dev/vulnerability/PYSEC-2021-613","summary":"","modified":"2023-12-06T01:01:33.927372Z","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-2021-811","url":"https://osv.dev/vulnerability/PYSEC-2021-811","summary":"","modified":"2023-12-06T01:01:33.927372Z","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).
