CVSS 7.8 · High EPSS 0,23%

Kerentanan Heap-based Buffer Overflow pada ggml llama.cpp. Skor CVSS 3.1 7.8 (High) menurut vulncheck.com.

Deskripsi (NVD)

llama.cpp builds b1886 through b7445 contain an integer overflow vulnerability in the LLaMA-Android JNI wrapper where the new_1batch() function multiplies sizeof(llama_seq_id) by an attacker-controlled n_seq_max parameter without overflow validation, causing heap buffer allocation to wrap and allocate insufficient memory. Attackers can exploit this by providing a crafted n_seq_max value through a malicious model file or JNI call to trigger heap corruption and achieve denial of service or arbitrary code execution on Android applications using the LLaMA-Android binding.
