{"id":"CVE-2022-29194","summary":"Missing validation causes denial of service via `DeleteSessionTensor` in TensorFlow","details":"TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of `tf.raw_ops.DeleteSessionTensor` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.","aliases":["BIT-tensorflow-2022-29194","GHSA-h5g4-ppwx-48q2"],"modified":"2026-05-28T03:54:35.572291068Z","published":"2022-05-20T21:10:12Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29194.json"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/session_ops.cc#L128-L144"},{"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-2022-29194.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-h5g4-ppwx-48q2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29194"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/cff267650c6a1b266e4b4500f69fbc49cdd773c5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"8727d035e7aa593720d16a5f57f70f3b5a93bd00"},{"fixed":"8a20d54a3c1bfa38c03ea99a2ad3c1b0a45dfa95"}]}],"versions":["v2.9.0-rc2","v2.9.0-rc1","v2.9.0-rc0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-29194.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
