An attacker can trigger a denial of service via a `CHECK`-fail in `tf.raw_ops.QuantizeAndDequantizeV4Grad`. This is because the implementation does not validate the rank of the `input_*` tensors. In turn, this results in the tensors being passes as they are to `QuantizeAndDequantizePerChannelGradientImpl`. However, the `vec<T>` method, requires the rank to 1 and triggers a `CHECK` failure otherwise. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2 as this is the only other affected version.","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-2021-29544","url":"https://www.suse.com/security/cve/CVE-2021-29544"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1186108 for CVE-2021-29544","url":"https://bugzilla.suse.com/1186108"}],"title":"SUSE CVE CVE-2021-29544","tracking":{"current_release_date":"2025-02-17T05:32:28Z","generator":{"date":"2023-02-15T03:43:18Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-29544","initial_release_date":"2023-02-15T03:43:18Z","revision_history":[{"date":"2023-02-15T03:43:18Z","number":"2","summary":"Current version"},{"date":"2024-11-12T01:37:20Z","number":"3","summary":"Current version"},{"date":"2025-02-15T05:09:39Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:32:28Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
