{"cve":"CVE-2022-41887","nvd":{"published":"2022-11-18T22:15:14.817","modified":"2026-06-17T05:03:59.920","status":"Modified","description":"TensorFlow is an open source platform for machine learning. `tf.keras.losses.poisson` receives a `y_pred` and `y_true` that are passed through `functor::mul` in `BinaryOp`. If the resulting dimensions overflow an `int32`, TensorFlow will crash due to a size mismatch during broadcast assignment. We have patched the issue in GitHub commit c5b30379ba87cbe774b08ac50c1f6d36df4ebb7c. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1 and 2.9.3, as these are also affected and still in supported range. However, we will not cherrypick this commit into TensorFlow 2.8.x, as it depends on Eigen behavior that changed between 2.8 and 2.9.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-131"],"references":["https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/cwise_ops_common.h","https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/keras/losses.py","https://github.com/tensorflow/tensorflow/commit/c5b30379ba87cbe774b08ac50c1f6d36df4ebb7c","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8fvv-46hw-vpg3","https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/cwise_ops_common.h"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-41887","score":0.00493,"percentile":0.42377,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8fvv-46hw-vpg3","url":"https://osv.dev/vulnerability/GHSA-8fvv-46hw-vpg3","summary":"Overflow in `tf.keras.losses.poisson`","modified":"2026-07-13T16:43:24.088183521Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.9.3"],"fixed":["2.9.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.10.0 <2.10.1"],"fixed":["2.10.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.9.3"],"fixed":["2.9.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.9.3"],"fixed":["2.9.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.10.0 <2.10.1"],"fixed":["2.10.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.10.0 <2.10.1"],"fixed":["2.10.1"]}]},{"id":"PYSEC-2026-3136","url":"https://osv.dev/vulnerability/PYSEC-2026-3136","summary":"Overflow in `tf.keras.losses.poisson`","modified":"2026-07-13T16:43:24.088183521Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.9.3",">=2.10.0 <2.10.1"],"fixed":["2.9.3","2.10.1"]}]},{"id":"PYSEC-2026-3297","url":"https://osv.dev/vulnerability/PYSEC-2026-3297","summary":"Overflow in `tf.keras.losses.poisson`","modified":"2026-07-13T16:43:24.088183521Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.9.3",">=2.10.0 <2.10.1"],"fixed":["2.9.3","2.10.1"]}]},{"id":"PYSEC-2026-970","url":"https://osv.dev/vulnerability/PYSEC-2026-970","summary":"Overflow in `tf.keras.losses.poisson`","modified":"2026-07-13T16:43:24.088183521Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.9.3",">=2.10.0 <2.10.1"],"fixed":["2.9.3","2.10.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
