{"cve":"CVE-2021-29590","nvd":{"published":"2021-05-14T20:15:14.817","modified":"2026-06-17T03:47:58.600","status":"Modified","description":"TensorFlow is an end-to-end open source platform for machine learning. The implementations of the `Minimum` and `Maximum` TFLite operators can be used to read data outside of bounds of heap allocated objects, if any of the two input tensor arguments are empty. This is because the broadcasting implementation(https://github.com/tensorflow/tensorflow/blob/0d45ea1ca641b21b73bcf9c00e0179cda284e7e7/tensorflow/lite/kernels/internal/reference/maximum_minimum.h#L52-L56) indexes in both tensors with the same index but does not validate that the index is within bounds. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://github.com/tensorflow/tensorflow/commit/953f28dca13c92839ba389c055587cfe6c723578","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-24x6-8c7m-hv3f","https://github.com/tensorflow/tensorflow/commit/953f28dca13c92839ba389c055587cfe6c723578","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-24x6-8c7m-hv3f"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:18:09.669877188+00:00"},"epss":{"cve":"CVE-2021-29590","score":0.00198,"percentile":0.09665,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-24x6-8c7m-hv3f","url":"https://osv.dev/vulnerability/GHSA-24x6-8c7m-hv3f","summary":"Heap OOB read in TFLite's implementation of `Minimum` or `Maximum`","modified":"2026-07-08T06:28:50.023617065Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]}]},{"id":"PYSEC-2021-227","url":"https://osv.dev/vulnerability/PYSEC-2021-227","summary":"","modified":"2023-12-06T01:01:08.036749Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]},{"id":"PYSEC-2021-518","url":"https://osv.dev/vulnerability/PYSEC-2021-518","summary":"","modified":"2023-12-06T01:01:08.036749Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]},{"id":"PYSEC-2021-716","url":"https://osv.dev/vulnerability/PYSEC-2021-716","summary":"","modified":"2023-12-06T01:01:08.036749Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
