{"cve":"CVE-2020-15192","nvd":{"published":"2020-09-25T19:15:14.480","modified":"2026-06-17T02:56:14.057","status":"Modified","description":"In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes a list of strings to `dlpack.to_dlpack` there is a memory leak following an expected validation failure. The issue occurs because the `status` argument during validation failures is not properly checked. Since each of the above methods can return an error status, the `status` value must be checked before continuing. 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:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-20"],"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-8fxw-76px-3rxv","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-2020-15192","score":0.00834,"percentile":0.57681,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8fxw-76px-3rxv","url":"https://osv.dev/vulnerability/GHSA-8fxw-76px-3rxv","summary":"Memory leak in Tensorflow","modified":"2026-07-08T06:28:32.038348867Z","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-2020-115","url":"https://osv.dev/vulnerability/PYSEC-2020-115","summary":"","modified":"2023-12-06T01:00:16.153082Z","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-2020-272","url":"https://osv.dev/vulnerability/PYSEC-2020-272","summary":"","modified":"2023-12-06T01:00:16.153082Z","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-2020-307","url":"https://osv.dev/vulnerability/PYSEC-2020-307","summary":"","modified":"2023-12-06T01:00:16.153082Z","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).
