{"cve":"CVE-2022-21728","nvd":{"published":"2022-02-03T11:15:08.020","modified":"2026-06-17T04:26:52.233","status":"Modified","description":"Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for `ReverseSequence` does not fully validate the value of `batch_dim` and can result in a heap OOB read. There is a check to make sure the value of `batch_dim` does not go over the rank of the input, but there is no check for negative values. Negative dimensions are allowed in some cases to mimic Python's negative indexing (i.e., indexing from the end of the array), however if the value is too negative then the implementation of `Dim` would access elements before the start of an array. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":8.1},"cwes":["CWE-125"],"references":["https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/framework/shape_inference.h#L415-L428","https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/ops/array_ops.cc#L1636-L1671","https://github.com/tensorflow/tensorflow/commit/37c01fb5e25c3d80213060460196406c43d31995","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-6gmv-pjp9-p8w8","https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/framework/shape_inference.h#L415-L428"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:27:20.926095847+00:00"},"epss":{"cve":"CVE-2022-21728","score":0.01134,"percentile":0.66505,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6gmv-pjp9-p8w8","url":"https://osv.dev/vulnerability/GHSA-6gmv-pjp9-p8w8","summary":"Out of bounds read in Tensorflow","modified":"2026-09-10T03:49:16.984403462Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.5.3"],"fixed":["2.5.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.6.0 <2.6.3"],"fixed":["2.6.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.7.0 <2.7.1"],"fixed":["2.7.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.5.3"],"fixed":["2.5.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.6.0 <2.6.3"],"fixed":["2.6.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.7.0 <2.7.1"],"fixed":["2.7.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.5.3"],"fixed":["2.5.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.6.0 <2.6.3"],"fixed":["2.6.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.7.0 <2.7.1"],"fixed":["2.7.1"]}]},{"id":"PYSEC-2022-107","url":"https://osv.dev/vulnerability/PYSEC-2022-107","summary":"","modified":"2026-07-13T16:43:13.231725269Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.5.3",">=2.6.0 <2.6.3"],"fixed":["2.5.3","2.6.3"]}]},{"id":"PYSEC-2022-52","url":"https://osv.dev/vulnerability/PYSEC-2022-52","summary":"","modified":"2026-07-13T16:43:13.231725269Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.5.3",">=2.6.0 <2.6.3"],"fixed":["2.5.3","2.6.3"]}]},{"id":"PYSEC-2026-3121","url":"https://osv.dev/vulnerability/PYSEC-2026-3121","summary":"Out of bounds read in Tensorflow","modified":"2026-07-13T16:43:13.231725269Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.5.3",">=2.6.0 <2.6.3",">=2.7.0 <2.7.1"],"fixed":["2.5.3","2.6.3","2.7.1"]}]}],"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).
