CVE-2026-9949: Use after free in Google Chrome
CVE-2026-9949 is a use-after-free vulnerability in the core component of Google Chrome on Windows 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 CVSS score provided, and no explicit remediation level is stated in the available data. The vendor advisory link is provided but does not explicitly confirm patch status in the input data. 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 core of Google Chrome on Windows platforms before version 148.0.7778.216. Exploitation requires prior compromise of the renderer process and could lead to sandbox escape via crafted HTML content. The Chromium project rates this vulnerability as high severity. The vendor advisory is available but does not explicitly state patch availability or remediation details in the provided data. The affected product is the desktop version of Google Chrome, not a cloud service.
Potential Impact
If exploited, an attacker with control over the renderer process could potentially break out of the Chrome sandbox, increasing the risk of executing code with higher privileges on the host system. This elevates the threat beyond typical renderer process compromise, potentially allowing broader system impact. No known active exploits have been reported, which may reduce immediate risk but does not eliminate it.
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. Users should update to Chrome version 148.0.7778.216 or later once available. Until then, no specific mitigations are detailed in the advisory or input data.
