CVE-2022-39106

Kernel interruption via unchecked sensor-driver write

Published Dec 6, 2022 · Updated Apr 24, 2025

Out-of-bounds write in the Unisoc sensor driver on affected Android 10 through 12 chipsets allows local users to interrupt the kernel. The driver writes beyond a stack buffer because it fails to check an input bound, but Unisoc has not disclosed the affected function or input field. Local access is required, and the published narrative does not specify whether the interruption is a crash, hang, or reboot.
