Vulnerability in LLaMA-Android JNI wrapper (CVE-2026-70639)
Summary
Vulnerability in LLaMA-Android JNI wrapper (CVE-2026-70639). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
