TensorFlow, an open source machine learning platform, has a vulnerability in its `FusedBatchNorm` kernels that allows heap OOB access (out-of-bounds memory reading, where a program tries to read data outside the memory space it's allowed to use). This bug affects multiple older versions of TensorFlow that are still supported.

TensorFlow, an open source platform for machine learning, has a vulnerability in its sparse matrix multiplication code where it can crash or behave unpredictably (undefined behavior) if matrix dimensions are 0 or less, because the code tries to write to an empty memory location (nullptr, a reference to nothing). When dimensions are invalid, the code should create an empty output but not write to it, otherwise it causes a heap OOB access (writing data outside the boundaries of allocated memory).

TensorFlow, an open source machine learning platform, has a vulnerability where the code that builds a control flow graph (the structure representing how data moves through a model) crashes when it assumes paired nodes exist but they don't. When the first node in a pair is missing, the code tries to use a null pointer (a reference to nothing), causing the program to crash.

TensorFlow, an open source machine learning platform, has a vulnerability where the shape inference code for `DeserializeSparse` (a function that converts serialized data back into sparse tensors, which are data structures that efficiently store mostly-empty matrices) can crash due to a null pointer dereference (trying to access memory that hasn't been allocated). This happens because the code incorrectly assumes the input tensor has a specific structure.

TensorFlow, an open source machine learning platform, has a bug in its shape inference code for the `tf.ragged.cross` function where it tries to use a null pointer (a reference to nothing), causing undefined behavior. The vulnerability is caused by accessing an uninitialized pointer (a memory location that hasn't been set up yet).

TensorFlow, an open source machine learning platform, has a vulnerability in its shape inference code for the `tf.ragged.cross` function that allows reading data outside the bounds of allocated memory (an out-of-bounds read, which can cause crashes or expose sensitive data). The vulnerability affects multiple versions of TensorFlow and has been patched in newer releases.

TensorFlow, an open-source machine learning platform, has a vulnerability in its shape inference code for the `QuantizeV2` function that allows reading memory outside of the intended boundaries (heap OOB read, or out-of-bounds read) when the `axis` parameter is given a negative value less than -1. This happens because the code doesn't properly validate that negative axis values stay within acceptable bounds before accessing memory.

TensorFlow, an open source platform for machine learning, has a vulnerability in its shape inference functions for `QuantizeAndDequantizeV*` operations that can cause the program to read data outside the bounds of allocated memory (an out-of-bounds read, which is a memory safety error). This affects multiple versions of TensorFlow.

TensorFlow, an open source machine learning platform, has a bug in its Grappler optimizer (the part that optimizes computational graphs) where constant folding (simplifying calculations before running them) incorrectly tries to copy resource tensors (special data structures that shouldn't be modified), causing the program to crash. The issue affects multiple versions of TensorFlow.
