The issue is classified with medium severity by Chromium security. No CVSS score or known exploits in the wild have been reported at this time.
AI Analysis
Technical Summary
CVE-2026-87640 is an out-of-bounds read vulnerability (CWE-125) in the WebView component of Google Chrome on Android. It affects versions prior to 153.0.8010.36. The vulnerability permits a remote attacker, who has compromised the renderer process, to read memory outside the sandbox boundaries via a specially crafted HTML page. This could potentially lead to information disclosure. The vulnerability has been assigned medium severity by the Chromium security team. No detailed CVSS vector or score is available, and no known exploits have been reported.
Potential Impact
The vulnerability allows an attacker with control over the renderer process to read memory beyond the intended sandbox limits, potentially exposing sensitive information. However, exploitation requires prior compromise of the renderer process, limiting the attack surface. There are no reports of active exploitation in the wild.
Mitigation Recommendations
A fix is available in Google Chrome for Android version 153.0.8010.36 and later. Users and administrators should update to this version or a later one to remediate the vulnerability. Since this is not a cloud service, remediation depends on applying the update on affected devices. Patch status is confirmed by the version boundary in the description. No additional mitigations are indicated.
