Fixed in
- Google Chrome for Android 156.0.8078.47
- A later Android build, 156.0.8078.75, is listed on APKMirror; whether it contains this fix is unverified.
Workaround
- No vendor-documented workaround. Updating Chrome is the fix.
Exploitation
- No evidence of exploitation in the wild found. A third-party aggregator lists the CVE as not in the CISA KEV catalogue; not verified directly.
- No public proof of concept found.
- EPSS 0.00424 (about 0.4%).
Our recommendation
- Update Chrome on Android devices to 156.0.8078.47 or later.
- For managed devices, verify the installed version via MDM or Google Play.
- Other Chromium-based Android browsers: check with their vendors whether they include the fix.
