CVE-2025-6177 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. 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).. EPSS estimates a 0.08% chance of exploitation in the next 30 days.
