CVE-2026-9970: Use after free in Google Chrome
CVE-2026-9970 is a use-after-free vulnerability in the WebGL component of Google Chrome versions prior to 148. 0. 7778. 216. This flaw could allow a remote attacker who has already compromised the renderer process to potentially escape the browser's sandbox by using a specially crafted HTML page. The vulnerability is classified by Chromium as having high security severity. There is no explicit CVSS score provided, and no known exploits in the wild have been reported at this time.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition in the WebGL implementation of Google Chrome before version 148.0.7778.216. Exploiting this issue requires prior compromise of the renderer process, after which an attacker could leverage the flaw to perform a sandbox escape. The sandbox escape could allow the attacker to break out of the restricted execution environment, potentially leading to further system compromise. The issue was publicly disclosed on May 28, 2026, and is tracked as CVE-2026-9970.
Potential Impact
If exploited, this vulnerability could enable an attacker with control over the renderer process to escape the Chrome sandbox, increasing the potential impact of an already compromised renderer. This could lead to execution of code with higher privileges on the host system. However, exploitation requires prior compromise of the renderer process, limiting the initial attack vector. There are no known exploits in the wild as of the publication date.
Mitigation Recommendations
Google has released an update to Chrome version 148.0.7778.216 that addresses this vulnerability. Users and administrators should update to this version or later to remediate the issue. Since this is not a cloud service, remediation depends on applying the update to affected installations. Patch status is not explicitly confirmed in the advisory, but the presence of the fixed version indicates an official fix is available.
