CVE-2026-10016 Google CVE debrief

A use-after-free vulnerability in Google Chrome's DOM implementation prior to version 148.0.7778.216 allows remote attackers to execute arbitrary code within the browser sandbox via a crafted HTML page. The vulnerability stems from improper memory management in the Document Object Model (DOM), where a freed memory object is subsequently accessed, potentially leading to memory corruption and code execution. Google has assigned this a High severity rating. The fix is available in Chrome 148.0.7778.216 and later.

Who should care

Organizations relying on Google Chrome for business operations, security teams managing browser security posture, web developers testing against security updates, and end users with administrative privileges where browser compromise could escalate to system-level access.

Technical summary

The vulnerability exists in Chrome's DOM implementation where a use-after-free condition can be triggered through malicious HTML content. When DOM objects are freed but their pointers remain accessible, subsequent access to these dangling pointers can corrupt memory state. An attacker can exploit this to achieve arbitrary code execution within Chrome's sandboxed renderer process. The attack vector requires user interaction to load a crafted HTML page. Successful exploitation bypasses memory safety protections and could lead to further sandbox escape depending on additional vulnerabilities.

Defensive priority

high

Recommended defensive actions

  • Update Google Chrome to version 148.0.7778.216 or later immediately
  • Enable automatic browser updates to ensure rapid patching of future vulnerabilities
  • Implement application control policies to restrict execution of untrusted browser processes
  • Deploy web filtering to block access to untrusted or suspicious websites that may host exploit pages
  • Monitor for unusual browser process behavior or unexpected outbound connections from Chrome
  • Consider enabling site isolation features and enhanced security settings in Chrome enterprise policies
  • Review and update endpoint detection and response (EDR) rules to detect memory corruption indicators in browser processes
