CVE-2026-11645 is a high severity vulnerability in Google Chrome's V8 engine that allows out of bounds read and write operations. This flaw affects Chrome versions prior to 149.0.7827.103 and enables a remote attacker to execute arbitrary code within the browser's sandbox via a crafted HTML page. The vulnerability is related to memory safety issues classified under CWE-125 and CWE-787.
AI Analysis
Technical Summary
This vulnerability involves out of bounds memory access in the V8 JavaScript engine component of Google Chrome. Specifically, versions before 149.0.7827.103 are affected. Exploitation requires a user to visit a maliciously crafted HTML page, which can trigger arbitrary code execution inside the sandboxed environment of the browser. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability with network attack vector, low attack complexity, no privileges required, and user interaction needed.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code within the sandbox of the affected Chrome browser, potentially compromising confidentiality, integrity, and availability of the affected system. The sandbox limits the scope of impact but does not eliminate the risk of code execution.
Mitigation Recommendations
A fixed version, 149.0.7827.103, is available. Users and administrators should update to this version or later to remediate the vulnerability. The vendor advisory linked confirms the availability of this update. No additional mitigation steps are indicated by the vendor advisory.
