Official description
With physical access to the device and enough time an attacker is able to solder test leads to the debug footprint (or use the 6-Pin tag-connect cable). Thus, the attacker gains access to the bootloader, where the kernel command line can be changed. An attacker is able to gain a root shell through this vulnerability.

The underlying weakness: Hardware Internal or Debug Modes Allow Override of Locks
System configuration protection may be bypassed during debug mode.
How developers prevent this class of flaw
- Security Lock bit protections should be reviewed for any bypass/override modes supported. Any supported override modes either should be removed or protected using authenticated debug modes. Security lock programming flow and lock properties should be tested in pre-silicon and post-silicon testing.
