CVE-2026-19173: Out of bounds write in Google Chrome
Out of bounds write in Skia 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-2026-19173 is an out-of-bounds write vulnerability (CWE-787) in the Skia graphics library used by Google Chrome before version 151.0.7922.109. The flaw allows a remote attacker, who has compromised the renderer process, to potentially perform a sandbox escape by crafting a malicious HTML page. This could lead to increased privileges or further system compromise beyond the renderer sandbox. The vulnerability is recognized as high severity by Chromium security, but no CVSS score or patch details are currently available.
Potential Impact
If exploited, this vulnerability could enable an attacker with control over the renderer process to escape the sandbox protections of Google Chrome, potentially leading to execution of arbitrary code with higher privileges. This increases the risk of system compromise beyond the browser sandbox. However, there are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users and administrators should monitor official Google Chrome security advisories for updates and apply patches once available. Until then, limiting exposure to untrusted content and maintaining standard security best practices is advisable.
