The Real Culprit: How GNU IFUNC Made CVE-2024-3094 Possible

CVE-2024-3094 revealed a critical structural vulnerability that extends far beyond the xz-utils backdoor itself—the real culprit is GNU IFUNC's design, which enables malicious code injection through system dependencies. This analysis exposes how Linux's dynamic linking architecture and software supply chain dependencies can be weaponized, affecting critical infrastructure globally. Understanding these systemic weaknesses is essential for preventing future attacks that exploit the connections between applications rather than individual vulnerabilities.
