Technical details

The Mirostat Sampler component in src/llama-sampler.cpp fails to guard against non-finite (NaN or infinity) logits and probabilities, resulting in undefined behavior (float-cast-overflow) or assertion failures. Both Mirostat v1 and v2 variants are reachable remotely via the llama-server interface when mirostat=1 or mirostat=2, allowing an attacker to cause an abort or crash without authentication.

Affected products

ggml-org llama.cpp up to 0.7.0
