CVSS 8.1 · High EPSS 0,70%

Kerentanan Integer Overflow or Wraparound pada ggml llama.cpp. Skor CVSS 3.1 8.1 (High) menurut vulncheck.com.

Deskripsi (NVD)

llama.cpp builds b4882 through b9058 contain a heap buffer overflow vulnerability in the KV cache state restore path where the state_read_data() function computes write size without overflow checking, allowing attackers with write access to the slot_save_path directory to corrupt heap memory. Attackers can craft malicious state files where cell_count multiplication overflows or exceeds tensor buffer allocation to write attacker-controlled bytes past buffer boundaries, potentially resulting in heap metadata corruption, model weight corruption, or arbitrary code execution via function pointer overwrite.
