CVE-2025-31710Public exploit

Local privilege escalation via engineermode command injection

Published Jun 3, 2025 · Updated Jun 3, 2025

Command injection in UNISOC chipset engineermode on Android 13 through 15 allows local users to gain elevated privileges via crafted input. The com.sprd.engineermode application passes insufficiently validated command text through its trusted access to the root-run cmd_skt service, allowing shell commands to execute. Reachability requires local device access and the exposed EngineerMode command interface; the published demonstration obtains a root shell while SELinux remains enforced.
