DescriptionCVE.org

Use after free in Views in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome versions prior to 148.0.7778.216 stems from a use-after-free condition in the Views UI component, allowing a remote attacker to execute arbitrary code if they can convince a user to perform specific UI gestures on a crafted HTML page. Chromium rates this as High severity and a vendor patch is available, but no public exploit has been identified at time of analysis.

Technical ContextAI

The vulnerability resides in Chrome's Views framework, the cross-platform UI toolkit used to render browser chrome elements (windows, menus, dialogs, buttons) that exists outside of the web content renderer sandbox. The root cause is CWE-416 (Use After Free), a memory safety flaw where the program continues to reference memory after it has been deallocated, enabling an attacker who controls subsequent heap allocations to manipulate freed object state. Because Views runs in the browser process rather than a sandboxed renderer, successful exploitation can yield code execution at a higher privilege level than typical renderer-bound bugs. The CPE cpe:2.3:a:google:chrome covers all Chrome distributions prior to the fixed build 148.0.7778.216.

RemediationAI

Vendor-released patch: update Google Chrome to 148.0.7778.216 or later on the Stable channel; the fix is delivered through Chrome's automatic update mechanism and a browser restart is required for it to take effect, so confirm restart compliance in managed fleets. Reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html and the upstream tracker at https://issues.chromium.org/issues/513609324, and watch for corresponding updates from Chromium-based browser vendors (Edge, Brave, Opera) which typically follow within days. If immediate patching is not feasible, compensating controls include restricting browsing to trusted sites via enterprise policy (URLBlocklist/URLAllowlist), enabling Site Isolation if not already on by default, and user awareness training to avoid interacting with unfamiliar prompts or UI elements on untrusted pages - note that these mitigations reduce but do not eliminate exposure since the trigger is a routine HTML page combined with user UI interaction.
