15-Year-Old GhostLock Flaw Enables Root and Container Escape on Most Linux Distros
Researchers at Nebula Security disclosed GhostLock (CVE-2026-43499), a Linux kernel vulnerability present in the codebase since 2011 that affects most mainstream distributions. The flaw allows any logged-in user to gain root privileges without requiring special permissions, unusual configurations, or network access.
Why it matters: System administrators and Linux users need to prioritize patching immediately, as any authenticated local user can escalate to root on vulnerable systems, exposing all data and systems to compromise.
