CVE-2024-43085

Locked-device data access via accessory timeout

Published Nov 13, 2024 · Updated Nov 16, 2024

Incorrect USB access control in Google Android 12 through 15 allows physically proximate attackers to access device contents while locked. UsbDeviceManager.handleMessage restores mScreenUnlockedFunctions after an accessory-mode function-switch timeout instead of disabling data transfer. A USB connection and a timed-out accessory-mode switch are required; no user interaction or additional execution privileges are needed.
