CVE-2022-39120

Kernel crash via missing sensor-driver bounds check

Published Oct 14, 2022 · Updated May 15, 2025

Buffer overflow in the UNISOC sensor driver for Android 10, 11, and 12 allows local users to crash the kernel through an out-of-bounds write. The driver performs a write without the required bounds check; UNISOC has not disclosed the affected function, buffer, or input field. Exploitation requires local access, high privileges, and user interaction, and the documented consequence is a kernel crash rather than code execution.
