Technical Summary
CVE-2026-87586 is an out-of-bounds read vulnerability in the ANGLE graphics engine used by Google Chrome before version 153.0.8010.36. This flaw enables a remote attacker to read memory outside the sandbox environment by delivering a specially crafted HTML page. The vulnerability is categorized under CWE-125 (Out-of-bounds Read). No further technical details or exploit code have been disclosed. The Chromium project rates this vulnerability as medium severity.
Potential Impact
Successful exploitation could allow an attacker to read memory outside the sandbox, potentially exposing sensitive information from the browser process memory. However, there is no evidence of active exploitation in the wild, and the impact is limited to information disclosure rather than code execution or privilege escalation.
Mitigation Recommendations
A fix is available in Google Chrome version 153.0.8010.36 and later. Users and administrators should update to this version or newer to remediate the vulnerability. Since this is a client-side application vulnerability, updating the browser is the primary mitigation step.
