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 scalar but there is no validation for this before accessing its value. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","published":"2022-05-20T21:55:18Z","modified":"2026-08-12T13:00:50.254496Z","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/13d38a07ce9143e044aa737cfd7bb759d0e9b400","label":"tensorflow/tensorflow@13d38a0"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/unsorted_segment_join_op.cc#L92-L95"},{"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-2022-29197.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-hrg5-737c-2p56"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29197"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/13d38a07ce9143e044aa737cfd7bb759d0e9b400"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:00:50.254496Z"}}
