{"id":"CVE-2020-15192","details":"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.","aliases":["BIT-tensorflow-2020-15192","GHSA-8fxw-76px-3rxv","PYSEC-2020-115","PYSEC-2020-272","PYSEC-2020-307"],"modified":"2026-04-11T21:19:56.134601Z","published":"2020-09-25T19:15:14.480Z","related":["GHSA-8fxw-76px-3rxv","openSUSE-SU-2020:1766-1"],"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"last_affected":"2b96f3662bd776e277f86997659e61046b56c315"},{"introduced":"0"},{"last_affected":"b36436b087bd8e8701ef51718179037cccdfc26e"},{"fixed":"22e07fb204386768e5bcbea563641ea11f96ceb8"},{"fixed":"fcc4b966f1265f466e82617020af93670141b009"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.2.0"},{"introduced":"0"},{"last_affected":"2.3.0"}]}}],"versions":["0.5.0","0.6.0","v1.1.0-rc1","v1.1.0-rc2","v1.12.1","v1.6.0-rc1","v1.9.0-rc2","v2.2.0","v2.2.0-rc0","v2.2.0-rc1","v2.2.0-rc2","v2.2.0-rc3","v2.2.0-rc4","v2.3.0","v2.3.0-rc0","v2.3.0-rc1","v2.3.0-rc2"],"database_specific":{"vanir_signatures_modified":"2026-04-11T21:19:56Z","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"15.2"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-15192.json","vanir_signatures":[{"source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","signature_version":"v1","signature_type":"Function","deprecated":false,"id":"CVE-2020-15192-28b47c62","digest":{"function_hash":"302909230814631908500873842520316055001","length":1068},"target":{"function":"TFE_HandleToDLPack","file":"tensorflow/c/eager/dlpack.cc"}},{"source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","signature_version":"v1","signature_type":"Function","deprecated":false,"id":"CVE-2020-15192-5c62b918","digest":{"function_hash":"24753109135250677179816536229137657275","length":40733},"target":{"function":"PYBIND11_MODULE","file":"tensorflow/python/tfe_wrapper.cc"}},{"source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","signature_version":"v1","signature_type":"Line","deprecated":false,"id":"CVE-2020-15192-61b62625","digest":{"threshold":0.9,"line_hashes":["203184394093938566735101442339476286402","5057783822461729014686159011822875566","276337694304556640652692797546760300494","324519683375647210480153687631467865768","150394200301454229501015301415659583403","193926713344694573779654214522808465940"]},"target":{"file":"tensorflow/python/tfe_wrapper.cc"}},{"source":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","signature_version":"v1","signature_type":"Line","deprecated":false,"id":"CVE-2020-15192-ba7f858a","digest":{"threshold":0.9,"line_hashes":["292945338278192546795872999715438919692","8499956686667079679287218720624198012","307114024074474464007071230750556435264","328636996453833581469835052556533486484","330074296641229322375849268324042839247","297098567421169699229427655622528681499","5005939368759929207605833461930312587","71125840436849761506943478301431655003","188619440248625237133937985021060796580","238407969739438406160217647691629800386","270117986294955159119535060630390044808","195004349352804827391322080325011119731","141444573330419127191167987337461451144","150569583603784431261765181427430532486","153618812154243453255623643549632453896","48503017837638972005747806247883235751","132225355395750670746629296731937542309","96071311886532311406221375120395617570","105512974983660108519637253708194445101","78023981141124778261323221962248709649","291525630689812036460554464906136495752","200733148512573282717005722123763233839"]},"target":{"file":"tensorflow/c/eager/dlpack.cc"}}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
