CVE-2026-0083

Local privilege escalation via NFC callback race

Published Jun 17, 2026 · Updated Jun 17, 2026

Use-after-free in Android 17 NFC allows local users to escalate privileges through a race in Nfc::eventCallback() without interaction. Concurrent callback execution can free an NFC object while Nfc::eventCallback() still accesses it, causing the function to use a stale reference. A local low-privileged context is required; successful exploitation raises privileges on the affected device without user interaction.
