CVE-2025-31711

Local system crash via null pointer dereference

Published Jun 3, 2025 · Updated Jun 3, 2025

A null pointer dereference in the cplog service on affected UNISOC chipsets running Android 13 through 15 allows local users to crash the system. UNISOC has not disclosed the cplog code path that accepts the trigger or identified which pointer becomes null before dereference. No additional execution privileges or user interaction are required, and the documented consequence is a local system crash.
