Google Chrome: Memory corruption in Payments component
Summary
A memory corruption flaw in the Payments component of Google Chrome before 156.0.8078.73 can be triggered by a crafted HTML page. A remote attacker who gets a user to open such a page can execute arbitrary code inside the browser sandbox. The attack needs no authentication, but the user has to load the page, for example via a link, a compromised site or an advertisement. The vendor rates the Chromium security severity as High and the CVSS base score is 8.8.
Affected
- Google Chrome (desktop) prior to 156.0.8078.73
The CVE record lists the affected range inconsistently; the vendor release notes are the reference.
Fixed in
- Google Chrome 156.0.8078.73 or later (per the vendor's Stable Channel Update of 27 Oct 2026; confirm the exact build on Google's release page)
Workaround
Unknown. No workaround was found in the sources; the only remedy is updating Chrome.
Exploitation
- No confirmed in-the-wild exploitation found.
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
- Not listed in the CISA KEV catalogue according to a third-party tracker.
- No public proof of concept found as of 26 Oct 2026.
Our recommendation
- Check the Chrome version on all endpoints and update to 156.0.8078.73 or later, or the latest stable build.
- Enforce browser restarts after updates through your management tooling.
- Check other Chromium-based browsers (for example Edge and Brave) with their respective vendors.
- Monitor the CISA KEV catalogue and the vendor advisory for changes.
