New Android Exploitation Strategy Achieves Root on Samsung, Xiaomi, and Other OEM Devices
Key points
- Exploits OEM-specific kernel driver Use-After-Free vulnerabilities.
- Bypasses OEM SELinux policies using OEM-specific sandbox escapes.
- Covers Samsung Galaxy S23-S26, Xiaomi, Oppo, OnePlus, and Realme flagships.
- Strategy focuses on reliability, portability, and universality across devices.
New Exploitation Strategy for Android Devices
A new exploitation strategy has been developed that allows an unprivileged Android application to achieve root privileges on various devices. This method focuses on vulnerabilities within code written by Original Equipment Manufacturers (OEMs) rather than generic Android or Linux components.
The strategy targets a page Use-After-Free (UAF) bug in an OEM-specific kernel driver. In cases where the OEM's SELinux policy restricts access to this driver, an OEM-specific sandbox escape is used to gain the necessary privileges.
Targeted Devices and Vulnerabilities
The strategy has been instantiated and tested on multiple devices, demonstrating its effectiveness. It covers all Samsung flagship devices from the Galaxy S23 through S26 series and recent Z series, a significant portion of Xiaomi mid-range to flagship devices, and recent Oppo, OnePlus, and Realme flagship devices.
A page UAF is a type of bug where a live reference to a physical memory page remains after the kernel has freed it. A sandbox escape allows code to transition from a lower-privilege process to a higher-privilege one.
Strategy Principles
The core principles guiding this exploitation strategy are reliability, portability, and universality. Reliability ensures near-100 percent success regardless of device defenses or customizations. Portability minimizes adjustments needed for different kernel versions, OEMs, chipsets, or devices. Universality aims to cover as many devices as possible with a single approach.
Impact and Future Details
This discovery highlights significant security vulnerabilities in OEM-specific code across a wide range of Android devices. The ability for an unprivileged app to gain root access poses a substantial risk to user data and device integrity.
