Severity CVSS v4.0:

Pending analysis

Type:

CWE-269 Improper Privilege Management

Publication date:

Description

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 &#39;fastboot oem disable_dm_verity&#39; 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.
