SukiSU Ultra
SukiSU-Ultra is a kernel-level privilege management tool for Android that grants and controls administrative access by patching kernel functions and loading custom modules. It functions as a kernel module framework that overwrites kernel function addresses to enhance system capabilities, and as a kernel patching utility for building device-specific rooted kernel images that preserve root access after system updates.
The project enforces fine-grained superuser permission management directly in the kernel, with per-application root privilege locking that restricts elevated access to a controlled environment for each app. It supports runtime kernel modifications through loadable modules, enabling advanced system enhancements without rebuilding the entire kernel, and provides a privilege profiler that manages how specific applications use elevated permissions within a controlled kernel environment.
The tool supports building custom kernel images with integrated root modules for specific device models, as well as Generic Kernel Images for universal Android compatibility. It runs on 64-bit ARM devices with full support, and extends kernel-level root functionality to legacy Android devices, non-GKI and GKI 1.0 hardware, and older kernels from version 3.4 through 3.18, with partial support for 32-bit ARM and x86_64 devices.
