| tiêu đề | ggml-org whisper.cpp ≤ 1.8.2 (confirmed on HEAD as of 2026-05-12) NULL Pointer Dereference |
|---|
| Mô tả | A crafted whisper model file with n_audio_state=0 and n_audio_layer>0 causes an unconditional process abort in whisper_model_load(). The loader reads hyperparameters from the model file without validating they are positive before using them as tensor dimensions. With n_audio_state=0, zero-dimension tensors are created with null data pointers. This triggers: (1) GGML_ASSERT(!ggml_is_transposed(a)) at ggml/src/ggml.c:3221 inside weight_buft_supported() — aborts the process unconditionally in all build types including release (-DNDEBUG does not suppress GGML_ASSERT); (2) null pointer passed to memcpy() at src/whisper.cpp:3688 when the loader reads weight data into tensor->data. A 124-byte crafted model file reproduces the crash. Confirmed on HEAD, Fedora 43 x86_64, release build — exit code 134 (SIGABRT).
