{"id":"PYSEC-2026-3383","summary":"FractionalMaxPool and FractionalAVGPool heap out-of-bounds acess","details":"### Impact\nAn input `pooling_ratio` that is smaller than 1 will trigger a heap OOB in [`tf.raw_ops.FractionalMaxPool`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/fractional_max_pool_op.cc) and [`tf.raw_ops.FractionalAvgPool`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/fractional_avg_pool_op.cc).\n\n### Patches\nWe have patched the issue in GitHub commit [216525144ee7c910296f5b05d214ca1327c9ce48](https://github.com/tensorflow/tensorflow/commit/216525144ee7c910296f5b05d214ca1327c9ce48).\n\nThe fix will be included in TensorFlow 2.11.0. We will also cherry pick this commit on TensorFlow 2.10.1.\n\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n","aliases":["BIT-tensorflow-2022-41900","CVE-2022-41900","GHSA-xvwp-h6jv-7472","PYSEC-2026-1049","PYSEC-2026-3261"],"modified":"2026-07-13T16:43:27.771777217Z","published":"2026-07-13T14:19:54.776276Z","references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-xvwp-h6jv-7472"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-41900"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/216525144ee7c910296f5b05d214ca1327c9ce48"},{"type":"PACKAGE","url":"https://github.com/tensorflow/tensorflow"},{"type":"PACKAGE","url":"https://pypi.org/project/tensorflow-cpu"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-xvwp-h6jv-7472"}],"affected":[{"package":{"name":"tensorflow-cpu","ecosystem":"PyPI","purl":"pkg:pypi/tensorflow-cpu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.4"},{"introduced":"2.9.0"},{"fixed":"2.9.3"},{"introduced":"2.10.0"},{"fixed":"2.10.1"}]}],"versions":["1.15.0","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.10.0","2.2.0","2.2.1","2.2.2","2.2.3","2.3.0","2.3.1","2.3.2","2.3.3","2.3.4","2.4.0","2.4.1","2.4.2","2.4.3","2.4.4","2.5.0","2.5.1","2.5.2","2.5.3","2.6.0","2.6.1","2.6.2","2.6.3","2.6.4","2.6.5","2.7.0","2.7.1","2.7.2","2.7.3","2.7.4","2.8.0","2.8.1","2.8.2","2.8.3","2.9.0","2.9.1","2.9.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-cpu/PYSEC-2026-3383.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
