The open‑source llama.cpp library released version b11529 on October 9, 2026. The update corrects a bug where a large offset could become negative, leading to an out‑of‑bounds write in the ggml_acc function. The fix adds a check before narrowing the offset, matching existing safety logic. The library continues to support CPU, CUDA, Vulkan, and other hardware across macOS, Linux, Android and Windows.

## The facts

- Release version: b11529
