CVE-2026-9899: Use after free in Google Chrome
CVE-2026-9899 is a use-after-free vulnerability in the ANGLE component of Google Chrome prior to version 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 rated with high severity and has a CVSS score of 8.3. No known exploits in the wild have been reported at this time. The vendor advisory linked corresponds to the Chrome stable channel update addressing this issue.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition in the ANGLE graphics engine within Google Chrome versions before 148.0.7778.216. Exploitation requires prior compromise of the renderer process and could lead to sandbox escape, allowing an attacker to execute code outside the browser's restricted environment. The issue is classified as high severity with a CVSS 3.1 score of 8.3, indicating significant impact on confidentiality, integrity, and availability. The official Google Chrome stable channel update released on or before May 28, 2026, includes a fix for this vulnerability.
Potential Impact
Successful exploitation could allow an attacker with control over the renderer process to escape the sandbox, potentially leading to arbitrary code execution with higher privileges than normally permitted within the browser environment. This elevates the risk of system compromise beyond the browser sandbox. There are no reports of active exploitation in the wild at this time.
Mitigation Recommendations
A fixed version of Google Chrome (148.0.7778.216 or later) has been released by Google to address this vulnerability. Users and administrators should update to this version or a later stable release to remediate the issue. Since this is a client-side application, patching the browser is the primary mitigation. No additional vendor-recommended mitigations or workarounds are indicated in the advisory.
