CVE-2022-39124

Kernel crash via unchecked sensor-driver write

Published Oct 14, 2022 · Updated May 14, 2025

An out-of-bounds write in the UNISOC sensor driver on Android 10, Android 11, and Android 12 allows local users to crash the kernel. The driver fails to check a boundary before writing sensor-related data, allowing an out-of-range write in kernel context; UNISOC has not disclosed the specific function or input path. A local low-privileged user must reach the driver; the documented consequence is a kernel crash and service interruption, with no confidentiality or integrity impact.
