CVE-2026-9997: Use after free in Google Chrome
Use after free in Input in Google Chrome prior to 148.0.7778.216 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
This vulnerability involves a use-after-free condition in the Input handling of Google Chrome before version 148.0.7778.216. Exploitation requires prior compromise of the renderer process and could lead to sandbox escape, increasing the attacker's privileges beyond the renderer sandbox. The issue is recognized as high severity by Chromium security but lacks a CVSS score and explicit remediation details in the provided information.
Potential Impact
Successful exploitation could allow an attacker with control over the renderer process to escape the sandbox, potentially leading to greater system compromise. However, exploitation requires prior compromise of the renderer process, which limits the initial attack vector. There are no known exploits in the wild as per the provided 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. Since this is not a cloud service, remediation depends on applying updates to affected Chrome versions. Until confirmation, users should update to version 148.0.7778.216 or later if available.
