Published Mar 24, 2020 · Updated Aug 5, 2024

Access control failure in SPENgesture on Samsung mobile devices with Android 7.1, 8.x, and 9.0 allows local users to read or modify user-input logs. Samsung has not published the faulty SPENgesture operation or access-control check that exposes those logs to arbitrary applications. A malicious application installed on an affected device can disclose captured input or alter the stored log, with no reported ability to execute code or interrupt service.
