CVE-2026-10298Public exploit

Process crash via unvalidated model dimensions

Published Jun 1, 2026 · Updated Jun 1, 2026

NULL pointer dereference in ggml.ai whisper.cpp 1.8.0 through 1.8.2 allows local users to crash a process via a crafted model file. whisper_model_load accepts a zero n_audio_state with positive n_audio_layer, creates zero-dimension tensors, and passes a null data pointer to memcpy or an invalid tensor to a release-build assertion. Exploitation requires control of a model file loaded by the application and interrupts only that process, with no reported data access or code execution.
