Google patches new Chrome zero-day bug exploited in attacks

Google has released an emergency security update to fix the third Chrome zero-day vulnerability exploited in attacks since the start of the year.

“Google is aware that an exploit for CVE-2025-5419 exists in the wild,” the company warned in a security advisory published on Monday.

This high-severity vulnerability is caused by an out-of-bounds read and write weakness in Chrome’s V8 JavaScript engine, reported one week ago by Clement Lecigne and Benoît Sevens of Google’s Threat Analysis Group.
