Worked on security remediation and reliability improvements for the AOSC-Dev/aosc-os-abbs repository, focusing on the OpenList component. Delivered a targeted update to OpenList 4.1.10, addressing CVE-2026-25059 and CVE-2026-25060 to reduce risk exposure and strengthen the system’s security posture. The approach included patch provisioning, systemd service integration, and ensuring proper reload behavior for stable runtime operation. All changes were consolidated into a single, well-documented commit with upstream collaboration and sign-off. Utilized Shell scripting and TOML for configuration management, demonstrating skills in DevOps, security patching, and system administration within a collaborative open-source workflow.
