Description

CVE-2016-5198 is an out-of-bounds memory access vulnerability in the Google Chromium V8 JavaScript engine. This flaw allows remote attackers to perform arbitrary read and write operations, potentially leading to code execution when a user visits a crafted HTML page. Multiple web browsers that use Chromium, such as Google Chrome, Microsoft Edge, and Opera, may be affected. Exploits for this vulnerability have been observed in the wild. No specific affected versions or patch information are provided in the input data.

Summary

The vulnerability CVE-2016-5198 exists in the Google Chromium V8 engine and involves out-of-bounds memory access. This enables remote attackers to manipulate memory beyond intended boundaries, facilitating arbitrary read/write operations. Successful exploitation can lead to remote code execution via a crafted HTML page. The issue impacts multiple Chromium-based browsers. The vulnerability is associated with CWE-125 (Out-of-bounds Read) and CWE-787 (Out-of-bounds Write). Known exploits have been reported in the wild. No vendor advisory or patch details are included in the provided data.

Impact

Exploitation of this vulnerability allows remote attackers to execute arbitrary code on affected systems by leveraging out-of-bounds memory access in the V8 engine. This can lead to full compromise of the browser process and potentially the underlying system. The vulnerability has been actively exploited in the wild, increasing the risk to users of affected browsers.

Mitigation

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users and administrators should monitor official Google Chromium security advisories for updates and apply patches promptly once available. Until a fix is applied, exercising caution when visiting untrusted websites is advisable.
