{"id":"CVE-2021-29515","details":"TensorFlow is an end-to-end open source platform for machine learning. The implementation of `MatrixDiag*` operations(https://github.com/tensorflow/tensorflow/blob/4c4f420e68f1cfaf8f4b6e8e3eb857e9e4c3ff33/tensorflow/core/kernels/linalg/matrix_diag_op.cc#L195-L197) does not validate that the tensor arguments are non-empty. 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-2021-29515","GHSA-hc6c-75p4-hmq4","PYSEC-2021-152","PYSEC-2021-443","PYSEC-2021-641"],"modified":"2026-05-30T09:15:38.399053Z","published":"2021-05-14T20:15:11.300Z","references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/a7116dd3913c4a4afd2a3a938573aa7c785fdfc6"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-hc6c-75p4-hmq4"}],"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":"a7116dd3913c4a4afd2a3a938573aa7c785fdfc6"}],"database_specific":{"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"],"cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*"}}],"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-2021-29515.json","vanir_signatures":[{"target":{"file":"tensorflow/core/kernels/linalg/matrix_diag_op.cc"},"digest":{"threshold":0.9,"line_hashes":["165664654517298026571641146603356550113","249371507493099438429987273074820076531","203389677054795751121491647277580682285","197076169969007512767254056688503135466","28034216127445773155573432905473337008","131000553446754305918048660454212796351"]},"signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/a7116dd3913c4a4afd2a3a938573aa7c785fdfc6","id":"CVE-2021-29515-edbc75d4","signature_type":"Line","deprecated":false}],"vanir_signatures_modified":"2026-05-30T09:15:38Z"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
