{"id":"CVE-2021-29526","details":"TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a division by 0 in `tf.raw_ops.Conv2D`. This is because the implementation(https://github.com/tensorflow/tensorflow/blob/988087bd83f144af14087fe4fecee2d250d93737/tensorflow/core/kernels/conv_ops.cc#L261-L263) does a division by a quantity that is controlled by the caller. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.","aliases":["BIT-tensorflow-2021-29526","GHSA-4vf2-4xcg-65cx","PYSEC-2021-163","PYSEC-2021-454","PYSEC-2021-652"],"modified":"2026-08-18T13:42:23.375739Z","published":"2021-05-14T20:15:11.807Z","references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/b12aa1d44352de21d1a6faaf04172d8c2508b42b"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-4vf2-4xcg-65cx"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"fixed":"0931ea3d985bb9c8fdd054a5e29c4129623c849b"},{"introduced":"2b96f3662bd776e277f86997659e61046b56c315"},{"fixed":"cfe0c80169ae984bcdc99ff6de7444164aaa8e07"},{"introduced":"b36436b087bd8e8701ef51718179037cccdfc26e"},{"fixed":"3929ffacfbef7c431e8397920d040aaf47acff19"},{"introduced":"582c8d236cb079023657287c318ff26adb239002"},{"fixed":"1923123d32ea41d92b70a27a3f6ecf0763b56f6c"},{"fixed":"b12aa1d44352de21d1a6faaf04172d8c2508b42b"}],"database_specific":{"cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.1.4"},{"introduced":"2.2.0"},{"fixed":"2.2.3"},{"introduced":"2.3.0"},{"fixed":"2.3.3"},{"introduced":"2.4.0"},{"fixed":"2.4.2"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2.1.3","v2.2.2","v2.3.2","v2.4.1","v2.1.2","v2.2.1","v2.4.0","v2.3.1","v2.2.0","v2.1.1","v2.3.0","v2.1.0","v2.1.0-rc0","v2.1.0-rc2","v2.1.0-rc1","v1.12.1","v1.9.0-rc2","v1.6.0-rc1","v1.1.0-rc2","v1.1.0-rc1","0.6.0","0.5.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-29526.json","vanir_signatures_modified":"2026-08-18T13:42:23Z","vanir_signatures":[{"digest":{"function_hash":"52885584389583554662580624570638774955","length":3358},"id":"CVE-2021-29526-08382b02","signature_type":"Function","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/b12aa1d44352de21d1a6faaf04172d8c2508b42b","target":{"file":"tensorflow/core/kernels/conv_ops.cc","function":"ComputeConv2DDimension"},"deprecated":false},{"signature_type":"Line","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/b12aa1d44352de21d1a6faaf04172d8c2508b42b","target":{"file":"tensorflow/core/kernels/conv_ops.cc"},"deprecated":false,"digest":{"line_hashes":["173687339207235999576275656733559819231","121921501777671919028978630071452218039","13837838493346518855615118855234985226","139641609068420295264048637967276456390","62924923225575467146803769758524095167","88739273602309176012514572705318862526","256969225563047733359944909391490043756","289231885011739864568055639467248493785","123914790918687186096113325014614741342","162725975339914580946836678758534093446","160026932477560776312510624912548423962"],"threshold":0.9},"id":"CVE-2021-29526-4983cc65"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
