Technical details
A vulnerability exists in the `whisper_model_load` function within `ggml/src/ggml.c` (and `src/whisper.cpp`) of whisper.cpp. The root cause is a failure to validate hyperparameters, such as `n_audio_state`, when reading from a model file. If these values are set to zero, the loader creates zero-dimension tensors with null data pointers. Subsequent operations, such as `memcpy` or `ggml_mul_mat`, trigger a null pointer dereference or a `GGML_ASSERT` failure, leading to a process crash (SIGABRT). This attack requires the ability to provide a local model file to the application. As of the advisory date, the project has been notified but a formal patch has not been confirmed.
Affected products
