CVE-2026-9931: Use after free in Google Chrome
CVE-2026-9931 is a high-severity use-after-free vulnerability in the GPU component of Google Chrome before version 148.0.7778.216. It allows a remote attacker who has already compromised the renderer process to potentially escape the sandbox by using a specially crafted HTML page. The vulnerability affects desktop versions of Chrome and has a CVSS score of 8.3, indicating a high impact on confidentiality, integrity, and availability. No known exploits in the wild have been reported at this time. The vendor advisory linked does not explicitly confirm patch availability or remediation status.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition in the GPU subsystem of Google Chrome prior to version 148.0.7778.216. An attacker with control over the renderer process could leverage this flaw to perform a sandbox escape, which could lead to elevated privileges or execution of arbitrary code outside the browser sandbox. The issue is triggered via a crafted HTML page. The CVSS score of 8.3 reflects the network attack vector, high complexity, no privileges required, user interaction required, and complete impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could allow an attacker who has compromised the renderer process to escape the Chrome sandbox, potentially leading to arbitrary code execution on the host system with elevated privileges. This undermines the security boundary designed to isolate web content and protect the underlying operating system and user data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html for current remediation guidance. Until an official fix is confirmed, users should exercise caution when interacting with untrusted web content and ensure their Chrome browser is updated to the latest available version.
