CVE-2026-70638

CVE-2026-70638 affects the llama.cpp project, specifically the LLaMA-Android JNI wrapper. Versions b1886–b7445 are vulnerable due to an integer overflow in new_1batch(), which multiplies sizeof(llama_seq_id) by an attacker-controlled n_seq_max without overflow validation, causing the heap allocat...
