CVE-2025-31712

Local denial of service via unchecked buffer write

Published Jun 3, 2025 · Updated Jun 3, 2025

Out-of-bounds write in cplog on UNISOC chipsets running Android 13, 14, and 15 allows local users to interrupt the service. The cplog service performs a buffer write without checking the destination bounds; UNISOC has not published the exact function or input path. No execution privileges or user interaction are required, and exploitation requires local access; the reported consequence is denial of service.
