tools : reject truncated GGUF tensor data in split and export tools ( #30497 )
The problem here in the repo is gguf-split can silently produce corrupted tensor output when the input GGUF file is truncated. The fix is to add tensor-data bounds checks and short-read checks in gguf-split.cpp and export-lora.cpp, and a regression test that checks truncated input is rejected and valid tensor data is preserved.#
Bug : GGUF-split can silently produce corrupted tensor output when the input GGUF file is truncated. Fix : add short-read checks in gguf-split.cpp (in copy_file_to_file in split_strategy) and export-lora.cpp (in read_tensor_data of file_input) so that truncated input is rejected.
