CVE-2025-11131Network attack vector

Remote system crash via improper modem validation

Published Dec 1, 2025 · Updated Dec 1, 2025

Improper input validation in UNISOC T8100, T8200, T8300, and T9100 NR modems allows remote attackers to crash Android 13 through 16 devices. UNISOC has not disclosed the input field, parser, or validation error that lets untrusted network input reach the modem crash path. No authentication, additional execution privileges, or user interaction is required, and the documented consequence is service interruption from a system crash.
