Incomplete validation in `SparseReshape` results in a denial of service based on a `CHECK`-failure. The implementation(https://github.com/tensorflow/tensorflow/blob/e87b51ce05c3eb172065a6ea5f48415854223285/tensorflow/core/kernels/sparse_reshape_op.cc#L40) has no validation that the input arguments specify a valid sparse tensor. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2 and TensorFlow 2.3.3, as these are the only affected versions.","published":"2021-05-14T20:15:15.947Z","modified":"2026-08-07T16:50:12.634573Z","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":null,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.3.3"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.4.2"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.3.3"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.4.2"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.3.3"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.4.2"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/commit/1d04d7d93f4ed3854abf75d6b712d72c3f70d6b6","label":"tensorflow/tensorflow@1d04d7d"},"references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/1d04d7d93f4ed3854abf75d6b712d72c3f70d6b6"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9rpc-5v9q-5r7f"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T16:50:12.634573Z"}}
