CyberRota Analysis
AI-GeneratedThe LLaMA-Android JNI wrapper in specific builds of llama.cpp is vulnerable due to a race condition use-after-free, which arises from a lack of synchronization between memory operations in multi-threaded scenarios. This vulnerability allows attackers to exploit the situation by manipulating memory, potentially leading to remote code execution through arbitrary memory dereferencing. Android developers and organizations utilizing affected versions should prioritize addressing this vulnerability to mitigate the risk of exploitation.

Original NVD Description
llama.cpp builds b1886 through b7445 contain a race condition use-after-free vulnerability in the LLaMA-Android JNI wrapper where bench_1model() and free_1context() lack synchronization, allowing Thread A to operate on freed memory while Thread B concurrently frees the llama_context. Attackers can exploit this by performing heap spray with attacker-controlled data containing a fake vtable to hijack the vtable pointer at offset +0x30, causing llama_batch_allocr::clear() to dereference arbitrary memory and achieve remote code execution.
