Google has released an emergency security update for its Chrome browser after detecting active exploitation of a critical zero-day vulnerability, the first such case reported this year.
The flaw, already used in real-world attacks, allows hackers to execute malicious code simply by luring users to a specially crafted webpage.
The bug, which was tracked as CVE-2026-2441, originated from a ‘use-after-free’ memory error that exists in Chrome’s CSS engine. The flaw enables attackers to access browser memory, which should be inaccessible to them, to gain complete control over the system.
Security researchers have identified the exploit as extremely dangerous because it requires only that the user visit a compromised website, with no additional action needed for exploitation.
Google confirmed that the vulnerability had been exploited in the wild before the fix was issued. The company pushed updated versions of Chrome for Windows, macOS, and Linux, and restricted technical details to prevent further misuse until most users had installed the patch.
Chromium-based browsers such as Microsoft Edge, Brave, and Opera are also expected to roll out corresponding updates.
The development highlights the browser’s central role in the modern threat landscape. A single unpatched browser becomes an entry point for surveillance, data theft, and ransomware attacks because all work activities, payment processes, and communication methods now depend on web platforms.
Google patched multiple zero-days last year, underscoring how quickly threat actors weaponize newly discovered bugs.

Users should update Chrome immediately by going to the ‘About’ section in settings, then relaunch the browser to activate the fix. Experts say delaying updates, even by a few days, significantly raises the risk of compromise.
The episode serves as a reminder that routine browser updates now double as critical security shields in an increasingly hostile digital environment.
