Stephanie Domas, Canonical's Chief Security Officer, returns to What's in the SOSS to discuss critical open source challenges. She addresses the issues of third-party security patch versioning, the rise of software sovereignty, and how custom patches break SBOMs. Domas also explains why geographic code restrictions contradict open source principles and what the EU's Cyber Resilience Act (CRA) means for enterprises. She highlights Canonical's work integrating memory-safe components like sudo-rs into the next Ubuntu LTS. This episode challenges assumptions about supply chain security, software trust, and the future of collaborative development in a regulated world.
