A new open-source tool called Root My Galaxy is making waves in the Samsung modding scene. Built by developer BuSung-dev, the app aims to give temporary (“soft”) root access on selected high-end Galaxy phones — without unlocking the bootloader, without wiping data, and without tripping Samsung’s Knox e-fuse.

That combination is rare. Classic Samsung root usually means OEM unlock, custom images, Knox 0x1, and broken banking / Wallet / Secure Folder features. Root My Galaxy takes a different path: it uses a Linux kernel privilege-escalation issue known as GhostLock (CVE-2026-43499) to inject a KernelSU-based root environment at runtime.

What “soft root” means

• Root is temporary — it must be reapplied after every reboot

• Bootloader stays locked

• Knox is reported to remain intact on successful runs

• Features like Secure Folder, Samsung Wallet, and Play Integrity are reported to keep working in many cases

• No full persistent Magisk-style system rewrite of the verified boot chain

In short: powerful for advanced users, but not a permanent “set and forget” root.

Supported devices (Snapdragon-focused)

Public reporting currently points to Snapdragon Galaxy flagships, with Galaxy S25 Ultra listed as the most mature / fully working target. Porting and testing have also been mentioned for:

• Galaxy S25 / S25+ / S25 Edge

• Galaxy S24 / S24+ / S24 Ultra / S24 FE

• Galaxy Z Fold 7

Exynos variants (and devices like Z Flip 7 on Exynos) are not the current focus. Galaxy S26-class devices launching on newer kernels are also outside this exploit’s window.

Firmware / patch caveat

Root My Galaxy is tied to specific firmware profiles and security patch levels. Public coverage generally points to June 2026 (and in some community reports July 2026) builds. Samsung is widely expected to close the hole in a later security update — so this is a moving target, not a forever method.

How the project is structured

• App repo: github.com/BuSung-dev/Root-My-Galaxy

• Device payloads / profiles: Root-My-Galaxy-Payloads

The installer matches kernel release, build ID, ABI, and related fingerprints to an exact supported profile. Unsupported builds need new offsets — users are asked to open GitHub issues with full model + build strings.

Warnings before you try anything

• Use only on devices you own

• Kernel exploits are risky — instability, data loss, or unexpected side effects are possible

• Banking / DRM behavior can still change between builds

• Staying on an older security patch to keep an exploit alive means accepting known unpatched risks

• This is not an official Samsung tool

GSM Leaks take

Root My Galaxy is one of the most interesting Samsung root developments in years precisely because it attacks the old trade-off: root vs Knox. Even as a temporary soft-root solution with a narrow device/firmware window, it shows how kernel-level bugs can reshape what’s possible on locked flagships.

We’ll keep watching payload updates, newly tested models, and the inevitable Samsung patch cycle.
