Google Chrome: Improper input validation in Bluetooth
Summary
Google Chrome contains an improper input validation flaw in its Bluetooth component. A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The CNA rates the issue as CVSS 3.1 8.8 (High), with user interaction required. The sources do not state whether an additional prerequisite, such as a compromised renderer, is needed.
Affected
- Google Chrome (desktop) prior to 156.0.8078.47 according to the CNA record.
Fixed in
- Google Chrome 156.0.8078.47 or later (per the vendor's Chrome Releases post; verify the Windows and macOS builds, reported as 156.0.8078.47/.48, against the vendor post).
- Microsoft Edge 156.0.4314.42 or later (Chromium-based, related advisory).
Workaround
No workaround is documented. Update Chrome and restart the browser completely.
Exploitation
- No public proof of concept found.
- Not listed in CISA KEV according to a third-party source; not verified against CISA.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Update all Chrome and Edge installations to the fixed builds.
- Force a full browser restart on managed endpoints so that the update takes effect.
- Check Chromium-based applications, kiosks and embedded browsers, which may be updated separately.
- Apply the whole Chrome 156 release, which fixes 353 security issues.
- Monitor the Chromium bug tracker entry and NVD for updated details.
