Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of `tf.raw_ops.UnsortedSegmentJoin` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. The code assumes `num_segments` is a positive scalar but there is no validation. Since this value is used to allocate the output tensor, a negative value would result in a `CHECK`-failure (assertion failure), as per TFSA-2021-198. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","published":"2022-05-20T22:40:13Z","modified":"2026-08-12T13:00:40.464758Z","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":{"score":0.00346,"percentile":0.2775,"asOf":"2026-08-23"},"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/20cb18724b0bf6c09071a3f53434c4eec53cc147","label":"tensorflow/tensorflow@20cb187"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/unsorted_segment_join_op.cc#L83-L14"},{"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-2022-29204.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/blob/master/tensorflow/security/advisory/tfsa-2021-198.md"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-hx9q-2mx4-m4pg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29204"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/20cb18724b0bf6c09071a3f53434c4eec53cc147"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/84563f265f28b3c36a15335c8b005d405260e943"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:00:40.464758Z"}}
