Google Chrome CVE-2026-5281 Zero-Day Actively Exploited, Update Now

Critical use-after-free flaw in Chrome Dawn WebGPU actively exploited demands immediate patching.

A critical zero-day use-after-free vulnerability in Google Chrome's Dawn WebGPU component is actively exploited. This advisory details the flaw, risks, and mitigation steps.

Understanding CVE-2026-5281 and Its Active Exploitation

On April 6, 2026, Google disclosed a critical zero-day vulnerability, CVE-2026-5281, affecting the Dawn WebGPU component in Chrome. This use-after-free flaw enables attackers to execute arbitrary code by tricking users into visiting malicious web pages.

Use-after-free means accessing memory after it has been freed, which can let attackers corrupt or take control of that memory. Here, the Dawn WebGPU API, which lets web apps access the GPU for hardware acceleration, mishandles memory, creating exploitable conditions.

This vulnerability is confirmed as actively exploited in targeted attacks, marking it as the fourth Chrome zero-day exploited in the wild in 2026. The trend signals attackers focusing on Chrome's new web platform features.

  • CVE-2026-5281 is a use-after-free vulnerability in Chrome's Dawn WebGPU component.
  • Exploitation can lead to remote code execution and full browser compromise.
  • This is the fourth Chrome zero-day exploited in the wild in 2026, indicating high threat level.
  • Google fixed the issue in Chrome version 114.0.5735.110 and later.
  • Delaying updates increases exposure to targeted attacks.

How to Mitigate CVE-2026-5281 Risk

Google's patch fixes the memory handling flaw in Dawn WebGPU. Version 114.0.5735.110 is available on desktop and mobile platforms.

Users should navigate to Chrome's About page to trigger update checks and restart the browser to complete installation.

IT teams need to prioritize this patch in management workflows to prevent exploitation, especially in managed environments where delays affect many users.

Enabling Chrome's automatic update feature helps keep browsers current with minimal user involvement. Failior’s platform helps organizations track browser versions and alerts on outdated clients, reducing risks from browser vulnerabilities and associated service disruptions.
