Safety vulnerability ID: 42474
The information on this page was manually curated by our Cybersecurity Intelligence Team.
TensorFlow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41227: In affected versions, the 'ImmutableConst' operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the 'tstring' TensorFlow string class has a special case for memory mapped strings but the operation itself does not offer any support for this datatype. The fix is also included in TensorFlow 2.7.0.

TensorFlow is an open source machine learning framework for everyone.
TensorFlow is an open source platform for machine learning. In affected versions the `ImmutableConst` operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the `tstring` TensorFlow string class has a special case for memory mapped strings but the operation itself does not offer any support for this datatype. 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. See CVE-2021-41227.
