Google has issued an urgent security update for its Chrome browser to address three high-severity vulnerabilities in the V8 JavaScript engine, which could lead to information leaks and system instability. The most critical flaw, CVE-2025-10890, allows for side-channel information leakage, whereas two additional vulnerabilities, CVE-2025-10891 and CVE-2025-10892, involve integer overflow conditions that could cause memory corruption. Users are advised to update their browsers promptly to mitigate potential threats, as the V8 engine processes JavaScript from all websites visited, emphasizing the need for robust cybersecurity measures in today’s digital landscape. This incident underscores the ongoing challenges in maintaining browser security and protecting user data from sophisticated cyberattacks.
