Google Chrome: Memory corruption in ANGLE allows sandboxed code execution
Summary
Google Chrome on Windows before 156.0.8078.47 contains a memory corruption flaw in ANGLE, Chromium's graphics translation layer. A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack requires user interaction, but no authentication. Chromium rates the issue High, and the CVSS score is 8.8.
Affected
- Google Chrome on Windows prior to 156.0.8078.47
- Chromium-based browsers that have not yet integrated the Chromium fix
Fixed in
- Google Chrome 156.0.8078.47 for Windows (vendor release of October 20, 2026; secondary sources also list .48, treat .47 as minimum)
Workaround
Unknown. No vendor-documented workaround. Updating Chrome is the fix.
Exploitation
- No evidence of exploitation in the wild found.
- No public exploit or proof of concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update all Windows Chrome installations to 156.0.8078.47 or later, and prioritise this on all workstations.
- Check Microsoft Edge and other Chromium-based browsers for their own fixed versions.
- Enforce automatic updates via policy and verify the installed version.
- Warn users about suspicious links and untrusted web pages until all systems are patched.
- Monitor CISA KEV and the vendor advisory for changes in exploitation status.
