CVE-2026-76044: Race condition in Google Chrome
A race condition vulnerability exists in the USB component of Google Chrome versions prior to 151.0.7922.169. This flaw allows a remote attacker who has already compromised the renderer process to potentially execute arbitrary code outside the browser sandbox by delivering a specially crafted HTML page. The vulnerability is rated with high severity and has a CVSS score of 8.3.
AI Analysis
Technical Summary
CVE-2026-76044 is a race condition vulnerability in the USB handling code of Google Chrome before version 151.0.7922.169. An attacker who has compromised the renderer process can exploit this flaw to execute arbitrary code outside the sandbox environment, increasing the impact of a renderer compromise. The vulnerability is classified under CWE-367 (Time-of-check Time-of-use (TOCTOU) Race Condition) and has a CVSS v3.1 base score of 8.3, indicating a high severity with network attack vector, high complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote code execution outside the sandbox from a compromised renderer process, significantly escalating the attacker's control over the affected system. This can lead to full system compromise depending on the privileges of the Chrome process.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.169. Users and administrators should update to this version or later to remediate the vulnerability. Since this is not a cloud service, patching the client software is required. No known exploits are currently reported in the wild.
