Worked on enhancing the reliability of the ELF loader within the phoenix-rtos/phoenix-rtos-kernel repository, focusing on kernel development and system programming using C. Addressed a critical bug by implementing robust handling for zero-size string sections in ELF64 files and validating the string name table to prevent misloads. Improved ELF header validation by correcting pointer references and introducing alignment checks for both program and section headers, reducing the risk of execution errors due to misalignment. These targeted changes increased boot stability and ensured safer kernel updates and module deployments, reflecting a methodical approach to low-level systems engineering and code traceability.
