{"id":"CVE-2021-29551","details":"TensorFlow is an end-to-end open source platform for machine learning. The implementation of `MatrixTriangularSolve`(https://github.com/tensorflow/tensorflow/blob/8cae746d8449c7dda5298327353d68613f16e798/tensorflow/core/kernels/linalg/matrix_triangular_solve_op_impl.h#L160-L240) fails to terminate kernel execution if one validation condition fails. 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-2021-29551","GHSA-vqw6-72r7-fgw7","PYSEC-2021-188","PYSEC-2021-479","PYSEC-2021-677"],"modified":"2026-04-11T17:12:46.371037Z","published":"2021-05-14T20:15:13.023Z","related":["GHSA-vqw6-72r7-fgw7"],"references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-vqw6-72r7-fgw7"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/480641e3599775a8895254ffbc0fc45621334f68"}],"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":"480641e3599775a8895254ffbc0fc45621334f68"}],"database_specific":{"versions":[{"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"}]}}],"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","v2.1.0","v2.1.0-rc0","v2.1.0-rc1","v2.1.0-rc2","v2.1.1","v2.1.2","v2.1.3","v2.2.0","v2.2.1","v2.2.2","v2.3.0","v2.3.1","v2.3.2","v2.4.0","v2.4.1"],"database_specific":{"vanir_signatures_modified":"2026-04-11T17:12:46Z","source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-29551.json","vanir_signatures":[{"source":"https://github.com/tensorflow/tensorflow/commit/480641e3599775a8895254ffbc0fc45621334f68","digest":{"line_hashes":["74362473220782431632780838319842760999","260372045928666315207474805728225556263","108861991243610225526089934665803922560","276626086644503099170362244807152488123","308498501487449830431061026699276082202","139746911372997557852875122922549895543","255811471497752850734057669701294187710","47756803923881015424712634433653988873","276124520409201514651002213935275666650","186455976464321243230485291658663883600","59806542684521672533551852535466300320","169085388540190716160684293314040180782","340107329169820916211807078514445268290","247365877593111735057917801813861043684"],"threshold":0.9},"id":"CVE-2021-29551-67b28d71","signature_type":"Line","signature_version":"v1","deprecated":false,"target":{"file":"tensorflow/core/kernels/linalg/matrix_triangular_solve_op_impl.h"}}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
