CVE-2025-48612 is an Android System component vulnerability in setDefaultKey of DefaultPaymentSettings.java caused by improper input validation. The flaw can allow an application to set the main user's default NFC payment setting when it should not be permitted to do so, including cross-profile scenarios involving a work profile and the primary user. By failing to properly validate the caller or supplied input when changing the default payment configuration, the affected component permits unauthorized modification of a security-relevant system setting. This issue affects Android 13 through 16 and can be exploited locally without user interaction or additional execution privileges.
