Google Chrome: Memory corruption in DOM allows sandboxed code execution
Summary
A memory corruption flaw in the DOM component of Google Chrome before 156.0.8078.47 can be triggered by a crafted HTML page. A remote attacker may potentially execute arbitrary code inside the browser sandbox. The victim must visit the malicious page. NVD rates the issue 8.8 (High), while Chromium rates it Medium.
Affected
- Chrome on Linux before 156.0.8078.47
- Chrome on Windows and macOS before 156.0.8078.47/.48
- Android Chrome builds before 156.0.8078.47
- Note: the CVE record's version range is malformed; use the vendor versions above.
- iOS is outside the scope of this CVE.
Fixed in
- Linux: 156.0.8078.47
- Windows and macOS: 156.0.8078.47/.48
- Android: 156.0.8078.47
Workaround
Unknown. Updating is the recommended remedy. Restart the browser after the update, because the fix only takes effect in a new browser process.
Exploitation
- CISA SSVC: exploitation none, automatable no, technical impact total.
- No evidence of exploitation in the wild was found; a third-party tracker lists the CVE as not in CISA KEV (not verified against CISA).
- No public proof of concept was found.
Our recommendation
- Inventory Chrome versions on Windows, macOS, Linux and Android.
- Verify that all endpoints run 156.0.8078.47 or later (156.0.8078.47/.48 on Windows and macOS) and that browsers were restarted after updating.
- Enforce updates centrally via managed update policies.
- Keep Chromium-based browsers such as Microsoft Edge on current builds.
- Re-check the Chromium bug and CISA KEV for changes in exploitation status.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
