Google Chrome: Memory corruption in Scroll allows code execution in sandbox
Summary
Google Chrome contains a memory corruption flaw in its Scroll component (CWE-119). A remote attacker can execute arbitrary code inside the browser sandbox if a user visits a crafted HTML page. Full compromise would normally require a further sandbox escape, which is not described in the CVE data. The CVSS 8.8 score is as listed in the CVE data and has not been verified against NVD.
Affected
- Google Chrome builds prior to 156.0.8078.47, per the CVE description
- The version range in the CNA record is internally inconsistent; the CVE description is treated as authoritative
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows, macOS, Linux, Android)
- Later point releases also include the fix
- Chromium-based browsers, such as Microsoft Edge, receive the fix through their own updates
Workaround
- No workaround is needed where the update is applied; the fix is a browser update.
- Enterprise policy controls or browser-level mitigations for Scroll: Unknown.
Exploitation
- Exploited in the wild: Unknown (none found; not checked against the CISA KEV catalogue).
- Public proof of concept: Unknown (none found).
- CISA SSVC assessment: exploitation none, automatable no, technical impact total.
Our recommendation
- Verify that all Chrome and Chromium-based browsers (including Edge) are at 156.0.8078.47 or later via Help > About Google Chrome.
- Ensure automatic browser updates are enabled and that browsers are restarted after updates.
- Prioritise endpoints with heavy web browsing and remind users about phishing links.
- Confirm the CVSS score and entry status in the NVD before relying on them.
