The Linux kernel is one of the largest and most active open-source projects, but its massive codebase and unique development culture create a high barrier to entry for newcomers. While many guides focus on the technical methodology of sending the first patch (like using git send-email), beginners often feel lost about how to build expertise and contribute sustainably afterward.

I propose to present a beginner's contribution guide focused on the Linux kernel security domain within the Operating Systems and Distributions track. This talk will be based on existing materials (e.g., LKCamp tutorials and DebConf etherpad notes) but will be enhanced with practical tips from my own experience in kernel security activities, reframing the discussion using the security subsystem as a case study for analysis and participation. The format will be a Lightning Talk covering how to overcome beginner hurdles, analysis methods, and engagement strategies, emphasizing the use of the staging tree and security-related TODO lists.
