CVE-2026-19140: Use after free in Google Chrome
Use after free in GPU in Google Chrome prior to 151.0.7922.109 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
CVE-2026-19140 is a use-after-free vulnerability in the GPU subsystem of Google Chrome before version 151.0.7922.109. Exploitation requires that the attacker has already compromised the renderer process. By leveraging this vulnerability through a crafted HTML page, the attacker may achieve sandbox escape, potentially leading to full system compromise. The vulnerability is classified under CWE-416 (Use After Free) and has a high severity rating with a CVSS 3.1 score of 8.3, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to sandbox escape from the renderer process, allowing an attacker to execute code with higher privileges than normally permitted within the browser sandbox. This can compromise system security by bypassing security boundaries intended to isolate web content.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.109. Users and administrators should update to this version or later to remediate the vulnerability. Since this is not a cloud service, remediation depends on applying the official browser update.
