What it is

Privilege Escalation in MiniOS in Google ChromeOS (16063.45.2 and potentially others) on enrolled devices allows a local attacker to gain root code execution via exploiting a debug shell (VT3 console) accessible through specific key combinations during developer mode entry and MiniOS access, even when developer mode is blocked by device policy or Firmware Write Protect (FWMP).
