{"cve":"CVE-2020-15195","nvd":{"published":"2020-09-25T19:15:14.743","modified":"2026-06-17T02:56:14.457","status":"Modified","description":"In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of `SparseFillEmptyRowsGrad` uses a double indexing pattern. It is possible for `reverse_index_map(i)` to be an index outside of bounds of `grad_values`, thus resulting in a heap buffer overflow. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-787","CWE-119","CWE-122"],"references":["http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html","https://github.com/tensorflow/tensorflow/commit/390611e0d45c5793c7066110af37c8514e6a6c54","https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-63xm-rx5p-xvqr","http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"],"products":["google:tensorflow","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15195","score":0.0095,"percentile":0.61269,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-63xm-rx5p-xvqr","url":"https://osv.dev/vulnerability/GHSA-63xm-rx5p-xvqr","summary":"Heap buffer overflow in Tensorflow","modified":"2026-07-08T06:27:32.770742745Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]}]},{"id":"PYSEC-2020-118","url":"https://osv.dev/vulnerability/PYSEC-2020-118","summary":"","modified":"2023-12-06T01:00:16.335009Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-275","url":"https://osv.dev/vulnerability/PYSEC-2020-275","summary":"","modified":"2023-12-06T01:00:16.335009Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-310","url":"https://osv.dev/vulnerability/PYSEC-2020-310","summary":"","modified":"2023-12-06T01:00:16.335009Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]}],"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).
