Google Chrome: Memory corruption in DOM allows sandboxed code execution
Summary
Google Chrome before 156.0.8078.79 contains a memory corruption flaw in its DOM handling. A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. The attack requires that a user visits the malicious page, for example via phishing or a compromised website.
Affected
- Google Chrome prior to 156.0.8078.79 (desktop)
Fixed in
- Google Chrome 156.0.8078.79 or later (Windows and Mac: 156.0.8078.79/.80; Linux: 156.0.8078.79)
Workaround
- Unknown. No workaround is documented; updating is the fix.
Exploitation
- Not listed in CISA KEV. Not known to be exploited in the wild.
- No public proof-of-concept found.
- EPSS: 0.20 % (percentile 10).
Our recommendation
- Update all Chrome installations to 156.0.8078.79 or later, including Extended Stable deployments.
- Verify versions via chrome://version or the asset inventory and relaunch the browser after updating.
- Deploy the complete Chrome 156 security update, not only this CVE.
- Confirm that other Chromium-based browsers in use have received their own patches.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
