Load-Time Division-by-Zero Crash in llama.cpp GGUF Metadata Parser
⚠️ This repository does not contain a machine learning model.
The file provided is intentionally malformed and exists solely for security research and vulnerability reproduction.
PoC Artifact
poc_fp_exception.gguf
Affected Component
llama.cpp— GGUF metadata parser
Vulnerability Summary
A malformed GGUF file can trigger a deterministic crash during model loading due to a division-by-zero condition in GGUF tensor shape validation.
The crash occurs at load time, before inference or tensor data processing, and results in immediate process termination.
Reproduction
From a llama.cpp build directory:
./llama-gguf poc_fp_exception.gguf r
