Google Chrome for Android: Memory corruption in Toolbar
Summary
A memory corruption flaw in the Toolbar component of Google Chrome for Android before 156.0.8078.47 allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attacker needs the victim to open a crafted HTML page, for example via a malicious or compromised website. The CVSS score is 8.8 (NVD), while Chromium rates the bug Low.
Affected
- Google Chrome on Android prior to 156.0.8078.47
- Desktop Chrome and Microsoft Edge are not covered by this Android entry; see vendor advisories for those builds
Fixed in
- Google Chrome for Android 156.0.8078.47 or later (later Android builds are reported, but unverified)
- Vendor advisory not read directly; verify against Google's release notes
Workaround
- Unknown. No vendor workaround is known; updating Chrome is the fix.
Exploitation
- No evidence of exploitation found. CISA SSVC: Exploitation none, Automatable no.
- Public proof of concept: none found.
Our recommendation
- Confirm Chrome on Android is at the latest build, at least 156.0.8078.47.
- Enable automatic updates via Google Play.
- Use MDM to enforce a minimum Chrome version on company devices, especially unmanaged or BYOD phones and tablets.
- Verify the fixed version against Google's official release notes before rollout.
