DescriptionCVE.org

A heap-based buffer overflow vulnerability exists in the GGUF library info->ne functionality of llama.cpp Commit 18c2e17. A specially crafted .gguf file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.

AnalysisAI

Remote code execution in llama.cpp (commit 18c2e17) is possible when a user opens a malicious .gguf model file, triggering a heap-based buffer overflow in the GGUF library's info->ne handling. Publicly available exploit code exists, though EPSS estimates exploitation probability at 0.48% (65th percentile), reflecting moderate but not widespread targeting risk against this AI inference runtime.
