Impact
A local attacker can trigger an out-of-bounds read leading to crashes or limited data leakage. They need local access to supply a crafted model file to the service.
Root cause
Improper bounds checking on the data_offset argument in gguf_init_from_file allows reading beyond allocated buffer boundaries when parsing GGUF files.
Affected systems
Tiiny-AI PowerInfer up to commit 8bd56d69906c9d2dba4d3bf6899763401e01a9a4.
