Use after free in V8 in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Remote code execution in Google Chrome's V8 JavaScript engine (versions prior to 151.0.7922.72) allows a remote attacker to run arbitrary code inside the renderer sandbox when a victim opens a crafted HTML page. The flaw is a CWE-416 use-after-free memory corruption issue; Google has released a fixed stable-channel build, and there is no public exploit identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the victim to open an attacker-controlled or compromised HTML page with malicious JavaScript in a vulnerable Chrome build (<151.0.7922.72) - the UI:R metric confirms user interaction is mandatory, so no fully unattended/wormable exploitation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 8.8 High) reflects network reachability, low complexity, no privileges, but required user interaction (visiting a page) and, critically, an unchanged scope - the description explicitly states code execution occurs 'inside a sandbox,' so the raw impact overstates real-world severity until paired with a sandbox-escape bug. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker hosts or compromises a web page containing crafted JavaScript that triggers the V8 use-after-free, then lures a victim to visit it (phishing link, malvertising, or a watering-hole site). When the page's script runs, the dangling pointer is exploited to execute arbitrary code within the browser's renderer sandbox. …
Remediation	Vendor-released patch: update Google Chrome to 151.0.7922.72 or later via the Chrome Releases stable channel update (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html); restart the browser to complete the update since Chrome staging leaves the old binary running until relaunch. … Detailed patch versions, workarounds, and compensating controls in full report.
