    Summary:

    Details: In is_device_locked and set_device_locked of keystore_keymaster_enforcement.h, there is a possible bypass of lockscreen requirements for keyguard bound keys due to a race condition. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
