During November 2025, Balázs worked on the DragonBluep/openwrt repository, focusing on kernel-level stability for embedded systems. He addressed a critical bug in the PHY detach workflow by implementing a safeguard against NULL dereference, which previously led to kernel panics when hardware reset was not performed. Using C programming and kernel development expertise, Balázs ensured that the driver was validated before dereferencing, thereby improving runtime reliability for devices using Airoha PHYs. His work demonstrated a deep understanding of Linux kernel internals and patch management, resulting in enhanced maintainability and reduced support requirements for OpenWrt deployments across supported hardware.
