A use-after-free vulnerability exists in the V8 JavaScript engine of Google Chrome versions prior to 153.0.8010.36. This flaw allows a remote attacker who has already compromised the renderer process to read memory within the sandbox by delivering a crafted HTML page. The vulnerability is classified with medium severity by Chromium security. There are no known exploits in the wild and no explicit patch information provided in the source data.
AI Analysis
Technical Summary
CVE-2026-87657 is a use-after-free vulnerability (CWE-416) in the V8 engine of Google Chrome before version 153.0.8010.36. It enables a remote attacker, who has compromised the renderer process, to read memory inside the sandbox environment via a specially crafted HTML page. This vulnerability could lead to information disclosure within the sandboxed process. No CVSS score or detailed vendor advisory is provided, and no known exploits have been reported.
Potential Impact
The vulnerability allows an attacker with control over the renderer process to read memory inside the sandbox, potentially exposing sensitive information. However, exploitation requires prior compromise of the renderer process, limiting the scope of impact. The Chromium security team rates this issue as medium severity.
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 fix is available. Until then, no specific mitigations are provided in the available data.
