AI Analysis

Impact

A use‑after‑free flaw in Chrome’s Bluetooth handling on macOS allows a remote attacker, after gaining control of the renderer process, to serve a crafted HTML page that triggers access to freed memory. This can cause the renderer to escape the browser sandbox and execute arbitrary code outside Chrome, potentially compromising the host system.

Affected Systems

Google Chrome on macOS versions prior to 150.0.7871.47 with Bluetooth enabled is impacted. Any user running these versions of Chrome with Bluetooth support enabled is vulnerable.

Risk and Exploitability

The vulnerability’s CVSS score of 9.6 indicates critical severity. The EPSS score is less than 1%, pointing to a very low likelihood of exploitation at the present time, and it is not included in the CISA KEV catalog. Exploitation requires the attacker to already have control over the renderer process and to deliver a crafted HTML page that triggers the use‑after‑free, after which a sandbox escape could compromise system security.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Chrome to version 150.0.7871.47 or later to apply the patch that fixes the Bluetooth use‑after‑free (CWE‑416).
  • If an update cannot be performed immediately, disable Bluetooth in Chrome via chrome://settings/bluetooth or block Bluetooth globally in macOS System Preferences to remove the vulnerable functionality.
  • Configure Chrome policies to deny Bluetooth permissions for untrusted or unknown sites, reducing the attack surface while awaiting an update.
