Detailed vulnerability description
The vulnerability allows a local user to disclose sensitive information.
The vulnerability exists due to an out-of-bounds read in the RaggedGather operation when processing invalid ragged tensor arguments. A local user can supply crafted inputs to trigger a read from outside the bounds of heap-allocated buffers to disclose sensitive information.
In debug mode, the same input triggers a CHECK failure.
