DescriptionCVE.org

Use after free in Enterprise in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Heap corruption via use-after-free in Google Chrome's Enterprise component allows a remote attacker to potentially execute arbitrary code when a victim visits a crafted HTML page, affecting all Chrome versions prior to 151.0.7922.72. Google rates the Chromium severity as Medium, but the CVSS 8.8 reflects full compromise of the browser process on successful exploitation; there is no public exploit identified at time of analysis and EPSS probability is low (0.18%). A vendor patch is available in the 151.0.7922.72 stable channel.

Technical ContextAI

The flaw is a CWE-416 Use-After-Free in the Enterprise component of Chromium, the open-source engine underpinning Google Chrome (CPE cpe:2.3:a:google:chrome). Use-after-free occurs when a pointer to heap memory continues to be used after that memory has been freed, letting an attacker reclaim the freed allocation with attacker-controlled data and corrupt the heap. In a browser context, an attacker triggers the dangling reference from JavaScript/HTML rendering, and Chrome's high-value renderer process makes such bugs a common stepping stone toward code execution, typically requiring a further sandbox escape for full system compromise. The 'Enterprise' subsystem indicates the vulnerable code path relates to Chrome's managed/policy features rather than the core DOM.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later via the Stable channel, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html; on most deployments Chrome auto-updates, so verify the version under chrome://settings/help and relaunch to apply. In managed enterprise fleets, push the update through your management tooling (e.g., Chrome Browser Cloud Management or OS patch management) and force a relaunch, since users who never restart the browser remain exposed. No specific vendor workaround is published; as an interim compensating control you can restrict browsing to trusted sites or enforce Chrome's site isolation and safe-browsing policies, accepting the trade-off that these reduce but do not eliminate exposure to a crafted-page attack.
