In the Airoha Bluetooth audio SDK, there is a possible permission bypass that allows access critical data of RACE protocol through Bluetooth LE GATT service. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
The CVSS score for this vulnerability is 8.8, categorizing it as high severity. This indicates a significant risk as attackers may leverage this vulnerability to gain unauthorized access to sensitive data without requiring user interaction or prior privileges.
Risk to organizations includes potential exposure of critical data transmitted via Bluetooth. Given the increasing reliance on Bluetooth technology in various applications, the implications of this vulnerability could be severe.
Organizations should prioritize patching immediately. While the vulnerability is currently awaiting analysis, the potential for exploitation necessitates proactive measures to secure affected systems.
Vulnerability Details
This vulnerability allows access to critical data through a permission bypass in the Airoha Bluetooth audio SDK. Specifically, it relates to the RACE protocol accessed via Bluetooth LE GATT service.
The CVSS vector is CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating that the attack can be executed over an adjacent network with low complexity, no privileges required, and no user interaction needed. The impacts on confidentiality, integrity, and availability are all rated as high.
The vulnerability was published on August 4, 2025, and is classified under CWE-306 for missing authentication for critical resources.
Technical Analysis
The root cause of this vulnerability stems from a failure to properly enforce permission checks within the Airoha Bluetooth audio SDK. This oversight allows unauthorized access to sensitive data of the RACE protocol.
The attack vector is classified as adjacent network, meaning an attacker must be within physical proximity to exploit the vulnerability. The attack complexity is low, and since no privileges are required, this significantly increases the risk of exploitation.
User interaction is not required, allowing for straightforward attacks. The high impact on confidentiality, integrity, and availability highlights the critical nature of the vulnerability.
Risk & Impact Analysis
Organizations utilizing the Airoha Bluetooth audio SDK are at significant risk due to this vulnerability. The ability for attackers to remotely escalate privileges without any prior access or user interaction represents a considerable threat.
Given the high CVSS score of 8.8, organizations should evaluate their exposure to this vulnerability and take immediate action. The potential blast radius could result in widespread unauthorized access to sensitive data transmitted over Bluetooth.
The urgency for remediation is high, and organizations should assess their security posture and implement mitigation strategies as soon as possible.
