CWE-843
AllowedAccess of Resource Using Incompatible Type ('Type Confusion')
Abstraction: Base · Status: Incomplete
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
1124 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2022-02-10 00:21 – Updated: 2024-11-13 22:31Impact
The implementation of MapStage is vulnerable a CHECK-fail if the key tensor is not a scalar:
import tensorflow as tf
import numpy as np
tf.raw_ops.MapStage(
key = tf.constant(value=[4], shape= (1,2), dtype=tf.int64),
indices = np.array([[6]]),
values = np.array([-60]),
dtypes = [tf.int64], capacity=0, memory_limit=0,
container='', shared_name='', name=None
)
Patches
We have patched the issue in GitHub commit f57315566d7094f322b784947093406c2aea0d7d.
The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

GHSA-GJQC-Q9G6-Q2J3
Vulnerability from github – Published: 2022-02-10 00:34 – Updated: 2024-11-07 22:28Impact
A malicious user can cause a denial of service by altering a SavedModel such that any binary op would trigger CHECK failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the dtype no longer matches the dtype expected by the op. In that case, calling the templated binary operator for the binary op would receive corrupted data, due to the type confusion involved:
functor::BinaryFunctor<Device, Functor, 1>()(
eigen_device, out->template flat<Tout>(),
input_0.template flat<Tin>(), input_1.template flat<Tin>(),
error_ptr);
If Tin and Tout don't match the type of data in out and input_* tensors then flat<*> would interpret it wrongly. In most cases, this would be a silent failure, but we have noticed scenarios where this results in a CHECK crash, hence a denial of service.
Patches
We have patched the issue in GitHub commit a7c02f1a9bbc35473969618a09ee5f9f5d3e52d9. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

"details": "### Impact\nA malicious user can cause a denial of service by altering a `SavedModel` such that [any binary op](https://github.com/tensorflow/tensorflow/blob/a1320ec1eac186da1d03f033109191f715b2b130/tensorflow/core/kernels/cwise_ops_common.h#L88-L137) would trigger `CHECK` failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the `dtype` no longer matches the `dtype` expected by the op. In that case, calling the templated binary operator for the binary op would receive corrupted data, due to the type confusion involved:\n\n```cc\nfunctor::BinaryFunctor\u003cDevice, Functor, 1\u003e()(\n eigen_device, out-\u003etemplate flat\u003cTout\u003e(),\n input_0.template flat\u003cTin\u003e(), input_1.template flat\u003cTin\u003e(),\n error_ptr);\n```\nIf `Tin` and `Tout` don\u0027t match the type of data in `out` and `input_*` tensors then `flat\u003c*\u003e` would interpret it wrongly. In most cases, this would be a silent failure, but we have noticed scenarios where this results in a `CHECK` crash, hence a denial of service.\n\n### Patches\nWe have patched the issue in GitHub commit [a7c02f1a9bbc35473969618a09ee5f9f5d3e52d9](https://github.com/tensorflow/tensorflow/commit/a7c02f1a9bbc35473969618a09ee5f9f5d3e52d9).\nThe fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.",

GHSA-GMJ9-H825-CHQ2
Vulnerability from github – Published: 2025-01-23 17:19 – Updated: 2025-01-23 23:17Impact
Via a type confusion bug in the CPython interpreter when using try/except* RestrictedPython could be bypassed.
We believe this should be fixed upstream in Python itself until that we remove support for try/except* from RestrictedPython.
(It has been fixed for some Python versions.)
Patches
Patched in version 8.0 by removing support for try/except* clauses
Workarounds
There is no workaround.
