Google Chrome for Android: Use-after-free in Media component
Summary
A use-after-free vulnerability in the Media component of Google Chrome on Android before 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a user to open a crafted HTML page, for example via a phishing link. Chromium rates the severity as Low, while CVSS 3.1 scores it 8.8 (High). The description does not mention a sandbox escape, so full device compromise would normally require a further vulnerability.
Affected
- Google Chrome on Android before 156.0.8078.47
Fixed in
- Google Chrome on Android 156.0.8078.47 or later
- Later Android builds may also contain the fix, but this could not be confirmed from primary sources.
Workaround
Unknown.
- No workaround is documented. Updating is the remedy.
Exploitation
- No evidence of exploitation in the wild was found at the time of research. Verify in the CISA KEV catalog.
- No public proof of concept was found.
Our recommendation
- Check the Chrome version on Android devices via MDM or Play inventory. Target 156.0.8078.47 at minimum, preferably the latest build.
- Confirm that Play Store auto-updates work on managed devices.
- Re-check the Chromium issue page and the CISA KEV catalog for status changes.
