  "message": "[HAL] Reject buffer view size overflows (#24992)\n\nRejects dense buffer views when shape multiplication or packed byte-size\ncalculation exceeds `iree_device_size_t`. Previously, overflowing\ndimensions could wrap to a small value and produce an undersized\nallocation request.\n\nThe size calculation now uses checked multiplication and addition while\npreserving zero-dimension behavior and sub-byte element packing. Dense\nview creation also verifies that the logical byte length fits within the\nbacking buffer, and reshape validates element counts before updating\nmetadata.\n\nTests cover:\n\n- Shape products that wrap to zero or one.\n- Packed-byte multiplication and addition overflow.\n- Maximum-size byte and sub-byte element counts.\n- Zero dimensions following otherwise overflowing dimensions.\n- Dense views larger than their backing buffers.\n- Overflowing reshape attempts.\n- Native and forced 32-bit `iree_device_size_t` configurations.\n\nTested with:\n\n- `iree/hal/buffer_view_util_test`\n- `iree/hal/string_util_test`\n- `iree/tooling/buffer_view_matchers_test`\n- `iree/tooling/function_io_test`\n- `iree/tooling/numpy_io_test`\n- Repository pre-commit hooks for all changed files\n\nThe original `iree-run-module` reproducer was not rerun because the\nvalidation build was configured as runtime-only without compiler tools.\n\nThis addresses the concrete buffer-view overflow case tracked in #3844.\nThe broader size-arithmetic audit remains open.\n\nAI agents assisted with understanding the codebase, writing tests, and\nreviewing the solution.\n\n---------\n\nSigned-off-by: goutamadwant \u003cworkwithgoutam@gmail.com\u003e",
