Critical Linux vulnerability exposes millions of systems with no patch in sight

The xz-utils backdoor exposed a critical gap in open-source software security: a malicious commit sat undetected in a widely-used compression library for months, nearly making it into major Linux distributions before discovery. The volunteer-driven maintenance model behind critical infrastructure software has limits. Downstream companies like Red Hat, Canonical, and Debian now choose between accepting unpatched systems or forking their own versions. The deeper issue is the erosion of confidence in supply chains that billions of connected devices depend on.
