CVE-2016-11041

Lockscreen bypass via enabled USB AT commands

Published Apr 7, 2020 · Updated Aug 6, 2024

Improper authentication in Samsung mobile devices with Android 4.4 allows physically proximate attackers to bypass the lockscreen via USB. The locked device accepts an AT command over its USB interface instead of disabling AT-command handling while the secure lockscreen is active. Physical access and a USB connection are required; public records do not identify the accepted command or the data exposed afterward.
