CVSS: 7.1EPSS: 0%CPEs: 6EXPL: 0CVE-2021-37682 – Use of unitialized value in TensorFlow Lite
https://notcve.org/view.php?id=CVE-2021-37682
TensorFlow is an end-to-end open source platform for machine learning. In affected versions all TFLite operations that use quantization can be made to use unitialized values. [For example](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/lite/kernels/depthwise_conv.cc#L198-L200). The issue stems from the fact that `quantization.params` is only valid if `quantization.type` is different that `kTfLiteNoQuantization`. However, these checks are missing in large parts of the code. • https://github.com/tensorflow/tensorflow/commit/4a91f2069f7145aab6ba2d8cfe41be8a110c18a5 https://github.com/tensorflow/tensorflow/commit/537bc7c723439b9194a358f64d871dd326c18887 https://github.com/tensorflow/tensorflow/commit/8933b8a21280696ab119b63263babdb54c298538 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-4c4g-crqm-xrxw • CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2021-37674
TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a denial of service via a segmentation fault in `tf.raw_ops.MaxPoolGrad` caused by missing validation. The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/maxpooling_op.cc) misses some validation for the `orig_input` and `orig_output` tensors. The fixes for CVE-2021-29579 were incomplete.

CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2021-37665 – Incomplete validation in MKL requantization in TensorFlow
https://notcve.org/view.php?id=CVE-2021-37665
TensorFlow is an end-to-end open source platform for machine learning. In affected versions due to incomplete validation in MKL implementation of requantization, an attacker can trigger undefined behavior via binding a reference to a null pointer or can access data outside the bounds of heap allocated arrays. The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/mkl/mkl_requantization_range_per_channel_op.cc) does not validate the dimensions of the `input` tensor. A similar issue occurs in `MklRequantizePerChannelOp`. The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/mkl/mkl_requantize_per_channel_op.cc) does not perform full validation for all the input arguments. • https://github.com/tensorflow/tensorflow/commit/203214568f5bc237603dbab6e1fd389f1572f5c9 https://github.com/tensorflow/tensorflow/commit/9e62869465573cb2d9b5053f1fa02a81fce21d69 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-v82p-hv3v-p6qp • CWE-20: Improper Input Validation •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2021-37677 – Missing validation in shape inference for `Dequantize` in TensorFlow
https://notcve.org/view.php?id=CVE-2021-37677
TensorFlow is an end-to-end open source platform for machine learning. In affected versions the shape inference code for `tf.raw_ops.Dequantize` has a vulnerability that could trigger a denial of service via a segfault if an attacker provides invalid arguments. The shape inference [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/ops/array_ops.cc#L2999-L3014) uses `axis` to select between two different values for `minmax_rank` which is then used to retrieve tensor dimensions. However, code assumes that `axis` can be either `-1` or a value greater than `-1`, with no validation for the other values.
