CVE-2025-48641

Local privilege escalation via NFC callback race

Published Mar 2, 2026 · Updated Mar 2, 2026

Use-after-free in Android 14, 15, 16, and 16 QPR2 allows local users to escalate privileges through the NFC system component. An asynchronous eventCallback thread dereferences the shared Nfc::mCallback immediately after Nfc::open destroys its object because a null check does not synchronize access. Low-privilege local access is required, exploitation needs no user interaction, and successful reuse yields elevated privileges.
