Kerentanan Integer Overflow or Wraparound pada ggml llama.cpp. Skor CVSS 3.1 7.8 (High) menurut vulncheck.com.

Deskripsi (NVD)

llama.cpp builds b1283 through b9058 contain an integer overflow vulnerability in the llama_batch_init() function where unchecked multiplications in malloc() calls can wrap past INT32_MAX when computing allocation sizes. Attackers can pass specially crafted parameters to trigger integer overflow, causing heap corruption and potentially achieving arbitrary code execution through subsequent batch operations that write past allocated buffer boundaries.
