{"id":"BIT-tensorflow-2022-23593","summary":"Segfault in `simplifyBroadcast` in Tensorflow","details":"Tensorflow is an Open Source Machine Learning Framework. The `simplifyBroadcast` function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault (hence, denial of service), if called with scalar shapes. If all shapes are scalar, then `maxRank` is 0, so we build an empty `SmallVector`. The fix will be included in TensorFlow 2.8.0. This is the only affected version.","aliases":["CVE-2022-23593","GHSA-gwcx-jrx4-92w2","PYSEC-2022-102","PYSEC-2022-157","PYSEC-2026-3193"],"modified":"2026-09-08T08:46:41.076253906Z","published":"2024-03-06T11:14:45.142Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/blob/274df9b02330b790aa8de1cee164b70f72b9b244/tensorflow/compiler/mlir/tfrt/jit/transforms/tf_cpurt_symbolic_shape_optimization.cc#L149-L205"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/commit/35f0fabb4c178253a964d7aabdbb15c6a398b69a"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-gwcx-jrx4-92w2"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23593"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.7.0"},{"fixed":"2.8.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2022-23593.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
