AI Analysis
Technical Summary
CVE-2026-87630 is an integer overflow vulnerability in the WebRTC implementation of Google Chrome before version 153.0.8010.36. Exploiting this flaw, a remote attacker can cause memory reads within the sandbox environment by using a crafted HTML page. The vulnerability relates to CWE-190 (Integer Overflow or Wraparound). There is no CVSS score provided, and no known exploits have been reported in the wild. The vulnerability affects Chrome browser versions prior to 153.0.8010.36.
Potential Impact
A successful exploit could allow a remote attacker to read memory inside the sandboxed environment of the Chrome browser. This could potentially lead to information disclosure from the browser's memory space. The impact is limited to memory disclosure within the sandbox and does not indicate code execution or privilege escalation based on the available data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should update Google Chrome to version 153.0.8010.36 or later once the update is available. Until then, exercise caution when visiting untrusted websites that might host crafted HTML content targeting this vulnerability.
