CVE-2025-31714

Privilege escalation through unverified Developer Tools input

Published Aug 18, 2025 · Updated Aug 18, 2025

Improper input validation in Unisoc Developer Tools on UWS6152 and related chipsets allows physically proximate attackers to elevate privileges. The Developer Tools component fails to verify an unspecified input before processing it; Unisoc has not disclosed the affected function, input format, or privileged operation. Physical access is required, no prior privileges or user interaction are needed, and successful exploitation compromises confidentiality, integrity, and availability.
