Sandboxed Remote Code Execution in Google Chrome Prerender
CVE-2026-110922 is a critical use-after-free vulnerability in the Prerender component of Google Chrome before version 155.0.8059.84. A remote attacker can trigger access to freed memory through a crafted HTML page and execute arbitrary code within the browser sandbox. The vulnerability also affects Chromium. Specific vulnerable functions and detailed triggering conditions have not been publicly disclosed.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation permits remote arbitrary code execution within the Chrome sandbox, compromising the affected sandboxed execution context. This vulnerability alone does not establish a sandbox escape or unrestricted access to the host operating system.
If you can’t patch tonight, do this now.
No vulnerability-specific temporary workaround has been documented.
Patch, then assume compromise.
Upgrade Chrome to a fixed Stable release: 155.0.8059.84 or later on Windows and Linux, or 155.0.8059.85 or later on macOS. Restart the browser to complete installation and verify the installed version on managed devices. For Chromium, install the distribution security update incorporating version 155.0.8059.84 or later. Fedora and EPEL update notices additionally require logging out and back in after installation.
