Google Chrome: Use-after-free in DataTransfer allows code execution in sandbox
Summary
Google Chrome versions before 156.0.8078.47 contain a use-after-free vulnerability in the DataTransfer component. A remote attacker can exploit it by luring a user to a crafted HTML page, which can execute arbitrary code inside the browser sandbox. Google rates the Chromium severity as Medium, while the CVSS base score is 8.8 (High).
Affected
- Google Chrome (desktop) prior to 156.0.8078.47
- Windows, macOS and Linux desktop builds of Chrome; other Chromium-based browsers may be affected depending on their Chromium version (vendor advisories to be checked)
Fixed in
- Google Chrome 156.0.8078.47 or later (Linux, Windows, macOS)
- Later stable builds are available; use the most recent stable build for your platform
- Ubuntu: chromium-browser package is not affected (installs the Chromium snap; check the snap separately)
Workaround
- Unknown. No vendor-documented workaround is known; apply the update.
Exploitation
- No evidence of in-the-wild exploitation found.
- No public proof of concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- EPSS score: unknown.
Our recommendation
- Update Google Chrome to 156.0.8078.47 or later, or the latest stable build, on all workstations now.
- Enforce updates centrally (managed Chrome policy, auto-update or a deployment tool) instead of relying on users.
- Check other Chromium-based browsers and the Chromium snap on Linux for their own fixed versions.
- Monitor for vendor updates and any signs of exploitation.
