Google has pushed an urgent security update for its Chrome browser, racing to patch a high-severity zero-day vulnerability that is currently being exploited by attackers in the wild. The flaw, tracked as CVE-2026-2441, affects the browser’s CSS component and could allow attackers to execute malicious code on a victim’s machine simply by having them visit a compromised webpage.
The vulnerability is described as a “Use after free in CSS.” In non-technical terms, this is a memory corruption error. It occurs when a program continues to use a pointer to a memory address after the memory at that address has been freed (deleted).
Attackers can exploit this “dangling pointer” to write their own malicious data into that memory space. When the browser tries to access the original data, it executes the attacker’s code instead. Because the flaw resides in the CSS (Cascading Style Sheets) engineβa core component used to render every modern websiteβthe attack surface is massive.
Google’s advisory comfirms: “Google is aware that an exploit for CVE-2026-2441 exists in the wild.” The vulnerability was reported on February 11, 2026, by security researcher Shaheen Fazim.
The fix is rolling out now to the Stable channel. Users are urged to verify their browser version and update immediately to close this security gap.
- Windows & Mac: Update to version 145.0.7632.75/.76
- Linux: Update to version 144.0.7559.75
To update, open Chrome, navigate to Settings > About Chrome, and let the download complete before relaunching the browser. Given the active exploitation status, administrators should prioritize this patch for all endpoints.
