ggml GGUF loader allows integer overflow and enum UB
Fuzzing found two paths where malformed model tensors trigger undefined behavior before validation finishes.
By tensor#gguf
llama.cpp GGUF reader accepts out-of-range type before checks
A crafted metadata key length can push an invalid enum into the parser, triggering undefined behavior on untrusted model files.
By tensorllama.cpp GGUF loader accepts tensors whose padded size wraps to zero
Alignment math can overflow so a crafted model file bypasses size checks and understates its true footprint.
By tensorllama.cpp adds GLM-5.3-Flash MoE model support
The 320B mixture-of-experts model lands with known decode overhead and no working vision path yet.
