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 in the Streaming component (CWE-416). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. User interaction is required, and the record does not describe a sandbox escape needed for full system compromise. Chromium rates the severity as Medium.
Affected
- Google Chrome versions before 156.0.8078.47 (per CVE description)
- The affected range in the CNA record is internally inconsistent, so the CVE description is used here
Fixed in
- Linux: 156.0.8078.47
- Windows and macOS: 156.0.8078.47 or 156.0.8078.48 (secondary sources, to be confirmed on the vendor advisory)
- Android: 156.0.8078.47 (secondary source)
- Debian: fixed package version unknown
- Ubuntu: chromium-browser marked not affected because it is a Snap wrapper; updates come through the Snap
Workaround
- No vendor workaround identified.
- Fully restart the browser after updating, because old browser processes may keep running.
Exploitation
- No known exploitation at the time of research.
- Not listed in CISA KEV; no public proof of concept found.
- CISA SSVC assessment: exploitation none, automatable no, technical impact total.
- EPSS score 0.00443 (per Vulners).
Our recommendation
- Update Chrome to the fixed version on all desktops and verify the version after restarting the browser.
- Check managed fleets for lagging or disabled auto-updates.
- Prioritise unmanaged devices and users who browse untrusted websites.
- Also update Chromium-based browsers such as Microsoft Edge and affected distribution packages.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
