A high-severity vulnerability has been identified in the Airoha Bluetooth audio Software Development Kit (SDK), which is used in numerous audio products. This flaw, designated CVE-2025-20702, could allow a nearby attacker to gain unauthorized access to a device's command protocol, potentially leading to data theft, unauthorized configuration changes, or a denial of service. Organizations using affected products should prioritize applying vendor-supplied security updates to mitigate this significant risk.

The vulnerability exists within the implementation of the Raelink Asynchronous Command Executive (RACE) protocol in the Airoha Bluetooth audio SDK. A flaw in the authentication or authorization mechanism allows an unauthenticated attacker within Bluetooth range to establish a connection and send malicious commands via the RACE protocol. Successful exploitation would grant the attacker unauthorized access to functions normally reserved for legitimate management and communication, enabling them to potentially read sensitive data, modify device settings, or disrupt normal operations.

This vulnerability presents a High severity risk, reflected by its CVSS score of 8.8. Exploitation could lead to significant business consequences, including the compromise of sensitive data handled by affected audio devices, such as call information or other personal data. An attacker could also manipulate device functionality, leading to a denial of service or unpredictable behavior, which could impact user safety or operational continuity. The widespread use of the Airoha SDK in consumer and enterprise audio products creates a broad attack surface, posing a reputational risk and potential financial liability for the organization if customer devices are compromised.

Immediate Action: The primary remediation is to apply the security updates provided by Airoha or the respective product manufacturer immediately. After patching, system administrators should monitor for any signs of post-remediation exploitation attempts and review device access logs for any anomalous activity that occurred prior to the update.

Proactive Monitoring: Implement enhanced monitoring of Bluetooth traffic for unusual or unauthorized connection attempts. Review system and application logs on devices utilizing the Airoha SDK for any errors or unexpected commands related to the RACE protocol. Security teams should be alert to any abnormal device behavior, such as unexpected reboots, configuration changes, or data transmission.

Compensating Controls: If immediate patching is not feasible, consider implementing compensating controls. This includes restricting physical access to sensitive areas where vulnerable devices are in use to limit an attacker's proximity. If possible, disable Bluetooth functionality on affected devices until they can be patched. Employing network segmentation and access control lists (ACLs) can also help limit the ability of unauthorized devices to interact with vulnerable systems.

Public Exploit Available: false

Due to the High severity (CVSS 8.8) of this vulnerability, we strongly recommend that organizations identify all affected products within their environment and apply the vendor-provided patches with the highest priority. Although there is no evidence of active exploitation at this time, the risk of unauthorized access and potential data compromise is significant. Adherence to the outlined remediation plan is critical to prevent future exploitation and protect the organization's assets and reputation.
