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.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"2b96f3662bd776e277f86997659e61046b56c315"},{"last_affected":"b36436b087bd8e8701ef51718179037cccdfc26e"},{"fixed":"22e07fb204386768e5bcbea563641ea11f96ceb8"},{"fixed":"fcc4b966f1265f466e82617020af93670141b009"}],"database_specific":{"cpe":["cpe:2.3:a:google:tensorflow:2.2.0:*:*:*:-:*:*:*","cpe:2.3:a:google:tensorflow:2.3.0:*:*:*:-:*:*:*"],"extracted_events":[{"introduced":"2.2.0"},{"last_affected":"2.2.0"},{"introduced":"2.3.0"},{"last_affected":"2.3.0"}],"source":["CPE_STRING","REFERENCES"]}}],"versions":["2.2.0","2.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-15192.json","vanir_signatures":[{"deprecated":false,"digest":{"function_hash":"302909230814631908500873842520316055001","length":1068},"id":"CVE-2020-15192-28b47c62","signature_type":"Function","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","target":{"file":"tensorflow/c/eager/dlpack.cc","function":"TFE_HandleToDLPack"}},{"deprecated":false,"digest":{"function_hash":"24753109135250677179816536229137657275","length":40733},"id":"CVE-2020-15192-5c62b918","signature_type":"Function","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","target":{"file":"tensorflow/python/tfe_wrapper.cc","function":"PYBIND11_MODULE"}},{"deprecated":false,"digest":{"line_hashes":["203184394093938566735101442339476286402","5057783822461729014686159011822875566","276337694304556640652692797546760300494","324519683375647210480153687631467865768","150394200301454229501015301415659583403","193926713344694573779654214522808465940"],"threshold":0.9},"id":"CVE-2020-15192-61b62625","signature_type":"Line","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","target":{"file":"tensorflow/python/tfe_wrapper.cc"}},{"deprecated":false,"digest":{"line_hashes":["292945338278192546795872999715438919692","8499956686667079679287218720624198012","307114024074474464007071230750556435264","328636996453833581469835052556533486484","330074296641229322375849268324042839247","297098567421169699229427655622528681499","5005939368759929207605833461930312587","71125840436849761506943478301431655003","188619440248625237133937985021060796580","238407969739438406160217647691629800386","270117986294955159119535060630390044808","195004349352804827391322080325011119731","141444573330419127191167987337461451144","150569583603784431261765181427430532486","153618812154243453255623643549632453896","48503017837638972005747806247883235751","132225355395750670746629296731937542309","96071311886532311406221375120395617570","105512974983660108519637253708194445101","78023981141124778261323221962248709649","291525630689812036460554464906136495752","200733148512573282717005722123763233839"],"threshold":0.9},"id":"CVE-2020-15192-ba7f858a","signature_type":"Line","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","target":{"file":"tensorflow/c/eager/dlpack.cc"}}],"vanir_signatures_modified":"2026-08-07T15:11:45Z"}}],"references":[{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8"},{"type":"EVIDENCE","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8fxw-76px-3rxv"}],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:opensuse:leap:15.2:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"15.2"},{"last_affected":"15.2"}],"source":"CPE_STRING","vendor_product":"opensuse:leap"}]},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
