Heap-data disclosure via malformed Tile input
Published Jun 27, 2022 · Updated Aug 3, 2024
Out-of-bounds write in MindSpore before 1.3.0 allows remote attackers to read heap data via malformed Tile operator input. The Tile shape-inference path accesses beyond heap-allocated buffers when its input data type is neither int nor int32. Exploitation requires attacker-controlled operator input to reach inference, and the published assessment limits impact to data disclosure.
