DescriptionCVE.org

Use after free in Views in Google Chrome on Windows prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Remote code execution in Google Chrome on Windows prior to 149.0.7827.53 allows a remote attacker to exploit a use-after-free condition in the Views component via a crafted HTML page. The flaw carries a CVSS 3.1 score of 8.8 with network attack vector and requires user interaction (visiting a malicious page), and no public exploit has been identified at time of analysis despite Google's vendor patch being released.

Technical ContextAI

The vulnerability resides in Chrome's Views framework, the cross-platform UI toolkit used by Chromium to render browser chrome elements such as menus, dialogs, and window decorations on Windows. CWE-416 (Use-After-Free) indicates that memory is referenced after it has been freed, typically because an object's lifetime is not properly synchronized with operations that reference it; attackers can groom the heap to place attacker-controlled data at the freed location, leading to controlled memory corruption and code execution within the renderer or browser process. Google's chrome-cve-admin team reported this via the Chromium issue tracker (issues.chromium.org/issues/501403820), and Chromium itself rated the security severity as Medium despite NVD's CVSS of 8.8.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 for Windows - upgrade immediately via Chrome's built-in updater (chrome://settings/help) or by redeploying the latest MSI for managed environments. Enterprise administrators using Chrome Browser Cloud Management or Group Policy should verify the rollout target version and force-restart Chrome processes since the fix only takes effect after a browser relaunch; details are in the Chrome Releases blog at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. As a temporary compensating control where patching is delayed, restrict browsing to trusted sites via SmartScreen/URL filtering or use an alternate browser for untrusted content - note this materially impacts user productivity and is only a short-term measure. Chromium-based derivatives (Edge, Brave, Opera, Vivaldi) likely require their own vendor-supplied updates that incorporate the same upstream fix.
