CVE-2021-25427

Paired-device information disclosure via SQL injection

Published Jul 8, 2021 · Updated Aug 3, 2024

SQL injection in Samsung Mobile Devices before SMR July-2021 Release 1 allows physically proximate attackers to read paired-device information. Samsung identifies Dialer Storage as the locus and says Bluetooth input validation was added, but does not disclose the vulnerable query or input path. Exploitation requires adjacent access; the documented consequence is disclosure of paired-device data without modification or service interruption.
