{"cve":"CVE-2020-15191","nvd":{"published":"2020-09-25T19:15:14.417","modified":"2026-06-17T02:56:13.927","status":"Modified","description":"In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes an invalid argument to `dlpack.to_dlpack` the expected validations will cause variables to bind to `nullptr` while setting a `status` variable to the error condition. However, this `status` argument is not properly checked. Hence, code following these methods will bind references to null pointers. This is undefined behavior and reported as an error if compiling with `-fsanitize=null`. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-252","CWE-20","CWE-476"],"references":["http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html","https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-q8qj-fc9q-cphr","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-2020-15191","score":0.009,"percentile":0.5966,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-q8qj-fc9q-cphr","url":"https://osv.dev/vulnerability/GHSA-q8qj-fc9q-cphr","summary":"Undefined behavior in Tensorflow","modified":"2026-07-08T06:27:37.433555194Z","packages":[{"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":[">=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":[">=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-2020-114","url":"https://osv.dev/vulnerability/PYSEC-2020-114","summary":"","modified":"2023-12-06T01:00:16.093597Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.2.1",">=2.3.0rc0 <2.3.1"],"fixed":["2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-271","url":"https://osv.dev/vulnerability/PYSEC-2020-271","summary":"","modified":"2023-12-06T01:00:16.093597Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.2.1",">=2.3.0rc0 <2.3.1"],"fixed":["2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-306","url":"https://osv.dev/vulnerability/PYSEC-2020-306","summary":"","modified":"2023-12-06T01:00:16.093597Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.2.1",">=2.3.0rc0 <2.3.1"],"fixed":["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).
