Over a two-month period, contributed kernel-level security and reliability improvements across analogdevicesinc/linux, torvalds/linux, and flipperdevices/u-boot repositories. Addressed a buffer overflow risk in the Xilinx display driver by replacing strscpy with fourcc_code, ensuring robust handling of DRM_FORMAT_XXX values and enhancing video pipeline safety using C and device driver expertise. Implemented secure CoreSight access restrictions for ARM64/ZynqMP platforms, disabling debug components by default under secure-boot in both Linux and U-Boot to reduce attack surface. Demonstrated disciplined kernel development, precise commit traceability, and a focus on embedded systems security through targeted patches and careful code review practices.
