Privileged lock-screen match disclosure via device logs
Published Sep 6, 2023 · Updated Sep 26, 2024
Information disclosure in Locksettings on Samsung Mobile Devices before SMR Sep-2023 Release 1 allows local users to read lock-screen match data. Locksettings writes lock-screen match information into the device log under overly broad conditions instead of suppressing the sensitive value. Access requires a privileged local context, and the reported consequence is disclosure of lock-screen match information without data modification.
