Impact

Android devices can be compromised through a use‑after‑free condition in multiple functions of bluetooth_cco.cc. The race condition may allow a local attacker to trigger memory corruption and gain system‑level execution privileges. This flaw is a classic example of a dangerous memory safety weakness that bypasses user authentication and does not require any user interaction.

Affected Systems

The vulnerability affects Android operating systems, specifically the Bluetooth stack shipped by Google. No specific OS version is listed, so all firmware builds that include the affected bluetooth_cco.cc code may be susceptible.

Risk and Exploitability

The CVSS base score of 6.4 indicates moderate severity; the EPSS score is not available, and the flaw is not in the CISA KEV catalog. Based on the description, the likely attack vector is local exploitation on the device, possibly through malicious Bluetooth traffic or an attacker physically present with the device. Because the race condition does not depend on user interaction, an adversary could trigger the flaw by generating competing Bluetooth requests or messages that manipulate shared state while the system is running. This could allow the attacker to write to arbitrary memory locations and elevate privileges.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the Android firmware to the latest security patch that fixes the Bluetooth CCO use‑after‑free flaw.
  • If a patch is not yet available, disable the Bluetooth radio or restrict its use via device management policies until the issue is resolved.
  • Continuously monitor device logs for anomalous system‑level activity that could indicate exploitation attempts.
  • Bluetooth traffic and enforce least‑privilege for applications that request Bluetooth access.
