DescriptionCVE.org

A vulnerability was found in ggml-org whisper.cpp 95ea8f9b. Affected is the function ggml_ftype_to_ggml_type of the file ggml/src/ggml.c. The manipulation of the argument ftype results in reachable assertion. The attack requires a local approach. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Local denial of service in ggml-org whisper.cpp 95ea8f9b via reachable assertion in ggml_ftype_to_ggml_type function. A local attacker with low privileges can cause a crash by supplying an invalid ftype argument. No public exploit identified; no patch available as vendor has not responded to issue report.

Technical ContextAI

whisper.cpp is a C++ port of OpenAI's Whisper speech recognition model using the ggml tensor library. The function ggml_ftype_to_ggml_type converts file type integers to ggml tensor types. CWE-617 indicates a reachable assertion where the program terminates unexpectedly when input validation fails, leading to denial of service. The affected product is identified by CPE cpe:2.3:a:ggml-org:whisper.cpp:*:*:*:*:*:*:*:*.

RemediationAI

No vendor-released patch identified at time of analysis. The project has been informed via issue report but has not responded. Until a fix is available, apply input validation to the ftype argument or restrict local access to the whisper.cpp binary to trusted users only. Monitor the issue tracker (https://github.com/ggml-org/whisper.cpp/issues/3924) for updates.
