File disclosure via implicit PendingIntent hijacking
Published Aug 5, 2022 · Updated Aug 3, 2024
PendingIntent hijacking in releaseAlarm in Samsung Charm before 1.2.3 allows local users to read files via an implicit intent. The releaseAlarm routine uses an implicit intent for a file-access PendingIntent, leaving the operation available for interception by another application. A malicious application running on the paired Android phone can exploit the condition without user interaction, exposing files that its own permissions would not allow it to read.
