Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, there is a potential for segfault / denial of service in TensorFlow by calling `tf.compat.v1.*` ops which don't yet have support for quantized types, which was added after migration to TensorFlow 2.x. In these scenarios, since the kernel is missing, a `nullptr` value is passed to `ParseDimensionValue` for the `py_value` argument. Then, this is dereferenced, resulting in segfault. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","published":"2022-05-20T22:25:14Z","modified":"2026-08-12T13:00:57.357120Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.6.4"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.7.2"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.8.1"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.6.4"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.7.2"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.8.1"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.6.4"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.7.2"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.8.1"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/commit/237822b59fc504dda2c564787f5d3ad9c4aa62d9","label":"tensorflow/tensorflow@237822b"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/python/eager/pywrap_tfe_src.cc#L296-L320"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/python/eager/pywrap_tfe_src.cc#L480-L482"},{"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-2022-29205.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-54ch-gjq5-4976"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29205"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/237822b59fc504dda2c564787f5d3ad9c4aa62d9"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:00:57.357120Z"}}
