Exposing Linux Security Blind Spots: io_uring Mechanism Can Bypass Mainstream Detection Tools

The ARMO research team recently revealed significant flaws in Linux runtime security tools, confirming that the io_uring interface allows rootkits (kernel-level malware) to bypass conventional monitoring solutions.Tests show that mainstream tools, including Falco, Tetragon, and even Microsoft Defender for Endpoint, are unable to detect attacks utilizing this mechanism. 01 Technical Principles “This mechanism allows user-space … Read more

Linux 'io_uring' Security Blind Spot Allows Stealthy Rootkit Attacks

Compiled by: Code Guardian A significant security gap in Linux runtime security caused by ‘io_uring’ can allow rootkits to operate undetected on systems while bypassing advanced enterprise security software. This vulnerability was discovered by security researchers at ARMO, who also developed a proof-of-concept rootkit named ‘Curing’ to demonstrate the practicality and feasibility of evading detection … Read more
