CVE-2026-70639
MEDIUMllama.cpp b1886–b7445 Null Pointer Dereference DoS via llama-android.cpp
Title source: cnaDescription
llama.cpp builds b1886 through b7445 contain a null pointer dereference vulnerability in the LLaMA-Android JNI wrapper where the bench_1model() function fails to validate the model context pointer before dereferencing it. Attackers can supply a malicious, corrupt, or truncated model file to trigger a null context condition, causing a SIGSEGV crash that terminates the Android application process and results in denial of service.
