Google Chrome: Memory corruption in Autofill on macOS
Summary
Memory corruption in the Autofill feature of Google Chrome for macOS prior to 156.0.8078.47 allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attacker must lure a user to a crafted HTML page, and no authentication is required. The CVE describes code execution inside the sandbox, not a full system compromise. The CVE record lists CVSS 3.1 8.8 (high), while the vendor rates the severity as Low.
Affected
- Google Chrome desktop for macOS prior to 156.0.8078.47 (per CVE record)
- Microsoft Edge on macOS, because it is Chromium-based, until it includes the Chromium fix (not confirmed by vendor advisory)
Fixed in
- Google Chrome 156.0.8078.47 (per CVE record)
- Latest stable Chrome release (recommended, as newer builds exist)
Workaround
Unknown. No vendor workaround is documented; updating is the only documented fix.
Exploitation
- No exploitation known at the time of the vendor release.
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.

Our recommendation
- Update Google Chrome and Microsoft Edge on all Macs to the latest stable release.

- Inventory Macs with Chromium-based browsers and check their versions.
- Monitor vendor advisories for further Chrome updates.
