CVE-2022-39127

Kernel denial of service via bounds-check omission

Published Oct 14, 2022 · Updated May 14, 2025

Out-of-bounds write in UNISOC sensor drivers on Android 10 through 12 allows local users to interrupt the kernel via driver input. The driver writes beyond a buffer because a required bounds check is absent; UNISOC has not disclosed the affected function or input field. Exploitation requires local access, and the vendor has not disclosed whether the kernel interruption is a crash, hang, or reboot.
