Google Chrome: Memory corruption in Core allows sandbox code execution
Summary
Google Chrome versions prior to 156.0.8078.47 contain a memory corruption flaw in the Core component (CWE-119). A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. Exploitation requires that the victim opens the page, and Google rates the Chromium severity as Low; a full compromise would normally also require a sandbox escape.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop)
- Microsoft Edge and other Chromium-based browsers that have not received the Chromium fix (HKCERT lists Edge 156.0.4314.42 or later as fixed)
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows and macOS build 156.0.8078.48 per Wikipedia)
- Microsoft Edge 156.0.4314.42 or later (per HKCERT)
- Linux distributions: check their Chromium package advisories; Ubuntu lists chromium-browser as not affected because it installs the Chromium snap, so check the snap version
Workaround
Unknown.
Exploitation
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total
- No public proof of concept found in the researched sources
- Not listed as known exploited in the sources checked (Strix record: KEV No)
Our recommendation
- Update Google Chrome and other Chromium-based browsers to 156.0.8078.47 or later (check the installed version, not only the deployment status)
- Make sure users restart the browser after the update so the fix takes effect
- Prioritise users who browse untrusted links or handle sensitive data, and systems that do not update automatically
- Monitor for exploitation news and update again promptly if a newer stable build is released
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
