An issue was discovered in OxygenOS before 4.0.3 for OnePlus 3 and 3T. The attacker can persistently make the (locked) bootloader start the platform with dm-verity disabled, by issuing the fastboot oem disable_dm_verity command. Having dm-verity disabled, the kernel will not verify the system partition (and any other dm-verity protected partition), which may allow for persistent code execution and privilege escalation.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
