CVE-2023-38467

Local service crash via missing urild bounds check

Published Sep 4, 2023 · Updated Oct 1, 2024

Out-of-bounds write in the UNISOC urild service on Android 10 through 13 chipsets allows local users with System privileges to crash the service. The urild service writes beyond a buffer because it fails to check an input boundary; UNISOC has not disclosed the specific function or input path. Exploitation requires local access with System execution privileges and affects availability only, with no reported data disclosure or modification.
