Google Chrome: Use-after-free in Streaming allows code execution in sandbox
Summary
Google Chrome before 156.0.8078.47 contains a use-after-free vulnerability (CWE-416) in the Streaming component. A remote attacker can use a crafted HTML page to execute arbitrary code inside the browser sandbox. User interaction is required (visiting the page), but no privileges. A full system compromise would also need a sandbox escape, which this CVE does not cover.
Affected
- Google Chrome desktop versions prior to 156.0.8078.47
- Chromium-based browsers that have not received the fix
Fixed in
- Google Chrome 156.0.8078.47 or later (version reported by the release post and NVD description)
- The newest stable 156 build is recommended. The vendor advisory could not be fully retrieved, so confirm the exact per-platform build there.
Workaround
Unknown. No vendor workaround has been identified. Apply the update.
Exploitation
- No known exploitation in the wild.
- A third-party tracker reports that the CVE is not in the CISA KEV catalog. This was not verified directly.
- No public proof of concept found.
- EPSS of 0.00443 (low exploitation probability estimate).
Our recommendation
- Verify that Chrome is at 156.0.8078.47 or later on all endpoints, preferably the latest 156 build.
- Verify that Chromium-based browsers such as Microsoft Edge are updated.
- Check that automatic updates work on managed devices.
- Monitor the vendor advisory and the CISA KEV catalog for changes.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
