CVE-2022-20468 is a medium-severity information disclosure vulnerability affecting multiple versions of the Android operating system, specifically Android 10 through Android 13, including Android 12L. The flaw exists in the Bluetooth Network Encapsulation Protocol (BNEP) implementation, specifically within the BNEP_ConnectResp function in the bnep_api.cc source file. The vulnerability arises due to an incorrect bounds check leading to a possible out-of-bounds read (CWE-125). This out-of-bounds read can cause the system to disclose local memory contents over Bluetooth. Notably, exploitation does not require any additional execution privileges, user interaction, or authentication, making it accessible to any nearby attacker capable of establishing a Bluetooth connection. The attack vector is remote but limited to the Bluetooth attack surface (AV:A), and the vulnerability impacts confidentiality (C:H) without affecting integrity or availability. The CVSS 3.1 base score is 6.5, reflecting a medium severity level. There are no known exploits in the wild at this time, and no patches are explicitly linked in the provided data, though it is likely addressed in recent Android security updates. The vulnerability could allow an attacker to glean sensitive information from device memory, potentially exposing user data or system information that could facilitate further attacks or privacy breaches. Given the widespread use of Android devices in Europe, this vulnerability represents a tangible risk, especially in environments where Bluetooth is enabled and devices are exposed to untrusted Bluetooth connections.

For European organizations, the primary impact of CVE-2022-20468 is the potential leakage of sensitive information from Android devices via Bluetooth. This could compromise user privacy and confidentiality of corporate data accessed or stored on mobile devices. Sectors with high reliance on mobile communications and Bluetooth peripherals—such as finance, healthcare, government, and critical infrastructure—may face increased risk if attackers exploit this vulnerability to gather intelligence or prepare for more sophisticated attacks. The vulnerability does not allow code execution or system disruption, so direct operational impact is limited. However, information disclosure can facilitate targeted phishing, social engineering, or lateral movement within networks. Given the prevalence of Android devices in Europe, especially in enterprise and consumer markets, the scope of affected systems is broad. The lack of required user interaction or privileges lowers the barrier for attackers, increasing the likelihood of opportunistic exploitation in environments with poor Bluetooth security controls or where devices are left discoverable. Organizations with policies that mandate Bluetooth usage or with many mobile endpoints should be particularly vigilant.

Ensure all Android devices are updated to the latest security patches provided by device manufacturers or Google, as this vulnerability is likely addressed in recent Android security bulletins. Implement strict Bluetooth usage policies within organizations, including disabling Bluetooth on devices when not in use and restricting device discoverability to trusted devices only. Use Mobile Device Management (MDM) solutions to enforce Bluetooth configuration policies and monitor Bluetooth connections for anomalous activity. Educate users about the risks of connecting to unknown or untrusted Bluetooth devices, emphasizing the importance of disabling Bluetooth in public or unsecured environments. Where possible, employ endpoint security solutions capable of detecting unusual Bluetooth traffic patterns or unauthorized connection attempts. For high-security environments, consider disabling Bluetooth entirely on corporate devices or using hardware-level controls to restrict Bluetooth functionality. Regularly audit and inventory Android devices within the organization to ensure compliance with patching and security policies related to Bluetooth usage.
