Google Chrome: Memory corruption in Bluetooth
Summary
Memory corruption in the Bluetooth component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs a victim to open a crafted HTML page, and no authentication is required. Code execution is limited to the sandbox, so a full compromise would likely also require a sandbox escape. The CVSS 3.1 base score is 8.8 (HIGH) according to the data provided, but this should be verified on NVD.
Affected
- Google Chrome prior to 156.0.8078.47 (CVE record)
- Microsoft Edge prior to 156.0.4314.42 (HKCERT bulletin, Edge is listed separately)
Fixed in
- Google Chrome 156.0.8078.47 or later 156.x stable build (Chrome Releases, 20 October 2026)
- Microsoft Edge 156.0.4314.42 or later (HKCERT)
Workaround
- Unknown. No vendor workaround was found. Applying the update is the remedy.
Exploitation
- CISA SSVC assessment: exploitation none, not automatable.
- No exploitation in the wild or public proof of concept was found in the sources checked.
Our recommendation
- Update Google Chrome to the latest 156.x stable build and Microsoft Edge to 156.0.4314.42 or later.
- Restart browsers after the update, as Chrome applies updates only after a relaunch.
- Check the browser versions on all managed devices, especially those that are rarely restarted.
- Verify the CVSS score and affected versions on NVD and the Chrome Releases page before final reporting.
