KernelSU is a kernel-based root solution for Android devices that provides superuser access and system-level privilege management.
The tool addresses the need for root access on Android by implementing a kernel-based approach rather than relying on userspace solutions. It operates through kernel integration, offering a `su` command and root access management system. The project includes a module system based on metamodules that enables systemless modifications to the system, and an app profile feature that allows fine-grained control over which applications can exercise root privileges.
KernelSU officially supports Android GKI 2.0 devices running kernel 5.10 and later, with backward compatibility for kernel 4.14 and above when manually built. The tool works on arm64-v8a and x86_64 architectures and extends support to WSA, ChromeOS, and container-based Android environments. Developers should be aware that recent kernel versions have introduced breaking changes affecting x86_64 compatibility that may cause kernel panics. Anyone considering adoption should verify device compatibility and review the installation and build documentation on the project website.
The project maintains active engagement with its user base, with nearly all open issues originating from external users rather than the core team, indicating substantial real-world adoption. Maintainers respond to new issues and pull requests within a day. Development activity centers on device support additions, bug fixes, and feature enhancements.
