Google Chrome: Memory corruption in DevTools allows code execution in sandbox
Summary
Memory corruption in the DevTools component of Google Chrome before 156.0.8078.47 can be exploited by a remote attacker. A victim who opens a crafted HTML page may have arbitrary code executed inside the browser sandbox. Google rates the issue Low in its own severity scale, while the NVD CVSS score is 8.8 (High).
Affected
- Google Chrome prior to 156.0.8078.47 (Windows, Mac, Linux)
- Chromium-based browsers that use the affected Chromium code base (vendor advisories must be checked for their own build numbers)
Fixed in
- Google Chrome 156.0.8078.47 or later (the CVE text names this build as the minimum fix; use the latest stable build)
Workaround
- No vendor workaround is known. Update Chrome to a fixed build instead.
Exploitation
- Exploitation in the wild: Unknown. No evidence found in the research notes; CISA KEV status not verified.
- Public proof of concept: None found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Google Chrome on all endpoints to the latest stable 156.x build and confirm that the browser has been relaunched after the update.
- Check that Chromium-based browsers such as Microsoft Edge are also updated to their fixed versions.
- Report and update devices that still run older versions.
- Restrict access to DevTools via enterprise policy where feasible, as general hardening.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
