In eager mode (default in TF 2.0 and later), session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference. The implementation(https://github.com/tensorflow/tensorflow/blob/eebb96c2830d48597d055d247c0e9aebaea94cd5/tensorflow/core/kernels/session_ops.cc#L104) dereferences the session state pointer without checking if it is valid. Thus, in eager mode, `ctx->session_state()` is nullptr and the call of the member function is undefined behavior. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2021-29518","url":"https://www.suse.com/security/cve/CVE-2021-29518"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1186108 for CVE-2021-29518","url":"https://bugzilla.suse.com/1186108"}],"title":"SUSE CVE CVE-2021-29518","tracking":{"current_release_date":"2025-02-17T05:33:20Z","generator":{"date":"2023-02-15T03:43:26Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-29518","initial_release_date":"2023-02-15T03:43:26Z","revision_history":[{"date":"2023-02-15T03:43:26Z","number":"2","summary":"Current version"},{"date":"2025-01-01T04:35:46Z","number":"3","summary":"Current version"},{"date":"2025-02-15T05:10:07Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:33:20Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
