CVE-2022-32642

Local privilege escalation via ccd race condition

Published Feb 6, 2023 · Updated Mar 26, 2025

Improper synchronization in MediaTek ccd on MT6879, MT6895, and MT6983 running Android 12 allows local users to escalate privileges. The ccd component permits a race between concurrent operations that corrupts memory; MediaTek has not disclosed the raced objects or operations. The path requires local access with existing System execution privileges, involves no user interaction, and grants higher privileges on an affected device.
