How We Obtained Root on Samsung S26 (Exynos 2600) – First Exploit After Bootloader Lock Removal
The team’s AI agent captured root privileges on the newly released Samsung S26 smartphone with Exynos 2600, marking the first post‑One UI 8 bootloader‑lock exploit, and demonstrated the vulnerability via a command‑wrapper app that runs entirely in the application context.
On the release day of Ubuntu 26.04, the authors’ AI agent succeeded in acquiring root privileges on Samsung’s latest flagship smartphone, the S26, which is powered by the Exynos 2600 chipset.
According to the authors, this represents the first known root exploit for the Exynos S26 since Samsung removed the bootloader unlocking option in One UI 8, effectively closing the traditional avenue for gaining deep system access.
The vulnerability can be triggered from within an application’s context, meaning no external flashing or bootloader manipulation is required. To showcase the exploit, the authors created a command‑wrapper application that demonstrates the root gain entirely through standard app execution.
