Google Chrome: Use after free in Media allows sandboxed code execution
Summary
Google Chrome versions prior to 155.0.8059.39 contain a use-after-free memory safety flaw in the Media component. A remote attacker can execute arbitrary code inside the browser sandbox by enticing a user to open a crafted HTML page. The vulnerability requires user interaction; the description does not confirm a full system compromise, which would need a separate sandbox escape.
Affected
- Google Chrome prior to 155.0.8059.39
- Chromium-based products that have not yet ingested the fix (Edge fixed build not verified)
Fixed in
- Google Chrome 155.0.8059.39 or later (Windows and Linux)
- Google Chrome 155.0.8059.40 or later (Mac)
- Debian chromium 155.0.8059.39-1~deb12u1 or later
Workaround
- No workaround is documented in the CVE record. Updating Chrome is the required fix.
- If updates are delayed, restrict browsing to trusted sites until the update is installed.
Exploitation
- No evidence of exploitation in the wild found.
- Not listed in the CISA KEV catalog.
- CISA SSVC: exploitation none, automatable no.
- No public proof-of-concept found.
Our recommendation
- Check all Chrome installations for version 155.0.8059.39 or later (Mac: 155.0.8059.40 or later).
- Force the update via managed deployment where Chrome is not updating automatically.
- Check Chromium-based browsers such as Microsoft Edge and Linux distribution packages for fixed builds.
- Monitor the CISA KEV catalog and vendor advisories for changes in exploitation status.
