Google Chrome: Memory corruption in Search allows code execution in sandbox
Summary
Google Chrome desktop versions before 156.0.8078.47 contain a memory corruption flaw (CWE-119) in the Search component. A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. The attack needs only that a user visits the malicious page, with no privileges required, so any user browsing the web is in scope.
Affected
- Google Chrome desktop before 156.0.8078.47 (per CVE record)
- Windows and macOS: sources also list builds before 156.0.8078.48 as affected
- Microsoft Edge before 156.0.4314.42 (per HKCERT bulletin)
- Ubuntu chromium-browser package: not affected (installs a Snap)
Fixed in
- Google Chrome 156.0.8078.47 or later (per CVE record)
- Windows and macOS: 156.0.8078.48 or later (per secondary sources; Google advisory not retrieved directly)
- Microsoft Edge 156.0.4314.42 or later (per HKCERT bulletin)
Workaround
Unknown. No workaround is documented in the sources; apply the update.
Exploitation
- No evidence of exploitation in the wild found.
- No public proof of concept found.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
- The CISA KEV catalogue was not checked directly.
Our recommendation
- Update Google Chrome to 156.0.8078.48 or later on Windows and macOS, and to 156.0.8078.47 or later on Linux.
- Update Microsoft Edge to 156.0.4314.42 or later.
- Relaunch the browser after updating and verify the version, because a pending update is not applied until restart.
- Inventory Chrome and Edge versions on all endpoints, prioritising shared and kiosk systems.
- Monitor for further Chrome security updates.

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