In affected versions the implementation of `SparseFillEmptyRows` can be made to trigger a heap OOB access. This occurs whenever the size of `indices` does not match the size of `values`. 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:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://github.com/tensorflow/tensorflow/commit/67bfd9feeecfb3c61d80f0e46d89c170fbee682b","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rg3m-hqc5-344v","https://github.com/tensorflow/tensorflow/commit/67bfd9feeecfb3c61d80f0e46d89c170fbee682b","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rg3m-hqc5-344v"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:24:39.218183596+00:00"},"epss":{"cve":"CVE-2021-41224","score":0.00208,"percentile":0.10937,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rg3m-hqc5-344v","url":"https://osv.dev/vulnerability/GHSA-rg3m-hqc5-344v","summary":"`SparseFillEmptyRows` heap OOB","modified":"2026-07-08T06:28:20.691095307Z","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-2021-416","url":"https://osv.dev/vulnerability/PYSEC-2021-416","summary":"","modified":"2023-12-06T01:01:35.189769Z","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-2021-633","url":"https://osv.dev/vulnerability/PYSEC-2021-633","summary":"","modified":"2023-12-06T01:01:35.189769Z","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-2021-831","url":"https://osv.dev/vulnerability/PYSEC-2021-831","summary":"","modified":"2023-12-06T01:01:35.189769Z","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).
