ChromeOS: Improper Protection against Electromagnetic Fault Injection (EM-FI)
CVE-2025-1566 is a high-severity improper protection against electromagnetic fault injection (EM-FI) vulnerability in ChromeOS from Google, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 16002.23.0 as the first without the flaw, so updating ChromeOS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update ChromeOS to 16002.23.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
