{"id":"CVE-2022-29206","summary":"Missing validation results in undefined behavior in `SparseTensorDenseAdd` in TensorFlow","details":"TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of `tf.raw_ops.SparseTensorDenseAdd` does not fully validate the input arguments. In this case, a reference gets bound to a `nullptr` during kernel execution. This is undefined behavior. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","aliases":["BIT-tensorflow-2022-29206","GHSA-rc9w-5c64-9vqq","PYSEC-2026-1032","PYSEC-2026-3235","PYSEC-2026-3365"],"modified":"2026-08-12T13:00:57.030693Z","published":"2022-05-20T22:15:13Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20","CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29206.json"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/sparse_tensor_dense_add_op.cc"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.6.4"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.7.2"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.8.1"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.9.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29206.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rc9w-5c64-9vqq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29206"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/11ced8467eccad9c7cb94867708be8fa5c66c730"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"fixed":"33ed2b11cb8e879d86c371700e6573db1814a69e"},{"introduced":"c256c071bb26e1e13b4666d1b3e229e110bc914a"},{"fixed":"dd7b8a3c1714d0052ce4b4a2fd8dcef927439a24"},{"introduced":"ce35e5c3a8efdb8161c6a85c8fb9ffb5bbdc9ffd"},{"fixed":"11ced8467eccad9c7cb94867708be8fa5c66c730"},{"fixed":"0516d4d8bced506cae97dc3cb45dbd2fe4311f26"},{"fixed":"8a20d54a3c1bfa38c03ea99a2ad3c1b0a45dfa95"}],"database_specific":{"cpe":["cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.7.0:rc0:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.7.0:rc1:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.8.0:-:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.8.0:rc0:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.8.0:rc1:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.9.0:rc0:*:*:*:*:*:*","cpe:2.3:a:google:tensorflow:2.9.0:rc1:*:*:*:*:*:*"],"extracted_events":[{"introduced":"0"},{"fixed":"2.6.4"},{"introduced":"2.7.0"},{"fixed":"2.7.2"},{"introduced":"2.7.0-rc0"},{"last_affected":"2.7.0-rc0"},{"introduced":"2.7.0-rc1"},{"last_affected":"2.7.0-rc1"},{"introduced":"2.8.0-NA"},{"last_affected":"2.8.0-NA"},{"introduced":"2.8.0-rc0"},{"last_affected":"2.8.0-rc0"},{"introduced":"2.8.0-rc1"},{"last_affected":"2.8.0-rc1"},{"introduced":"2.9.0-rc0"},{"last_affected":"2.9.0-rc0"},{"introduced":"2.9.0-rc1"},{"last_affected":"2.9.0-rc1"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"]}}],"versions":["2.7.0-rc0","2.7.0-rc1","2.8.0-NA","2.8.0-rc0","2.8.0-rc1","2.9.0-rc0","2.9.0-rc1","v2.9.0-rc2","v2.9.0-rc1","v2.6.3","v2.7.1","v2.9.0-rc0","v2.8.0","v2.8.0-rc1","v2.6.2","v2.8.0-rc0","v2.7.0","v2.6.1","v2.6.0","v2.6.0-rc2","v2.6.0-rc1","v2.6.0-rc0","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/cve-osv-conversion/osv-output/CVE-2022-29206.json","vanir_signatures_modified":"2026-08-12T13:00:57Z","vanir_signatures":[{"target":{"file":"tensorflow/core/kernels/sparse_tensor_dense_add_op.cc"},"deprecated":false,"digest":{"line_hashes":["221493233268286537659827014320394668101","82207426128829260309612597979246158047","5277208957558550673337177709160487983","151958456065648892737008559890577651035","211311739560596991482515868738725512339","219438528273262363439709378717835207052","185504399491295674597981208618368545979","175918897646274861063135720410660987565","63726725965755184658985833465422142945","261259081224229000059884329424767238589"],"threshold":0.9},"id":"CVE-2022-29206-1555f923","signature_type":"Line","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/11ced8467eccad9c7cb94867708be8fa5c66c730"},{"digest":{"function_hash":"192647852517683153220242599385909362107","length":1253},"id":"CVE-2022-29206-c01e98b0","signature_type":"Function","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/11ced8467eccad9c7cb94867708be8fa5c66c730","target":{"file":"tensorflow/core/kernels/sparse_tensor_dense_add_op.cc","function":"ValidateInputs"},"deprecated":false}]}}],"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"}]}
