TensorFlow — Vulnerability (CVE-2021-41222)
Date: 2021-11
Affected: google/tensorflow
Attack vector: other
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2021-41222
CWE: CWE-682
CVSS: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

TensorFlow is an open source platform for machine learning. In affected versions the implementation of `SplitV` can trigger a segfault is an attacker supplies negative arguments. This occurs whenever `size_splits` contains more than one value and at least one value is negative. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
