Overview<\/strong><\/p>\n

The cybersecurity industry is facing an alarming situation due to the discovery of a new vulnerability, CVE-2025-20702. This flaw exists in the Airoha Bluetooth audio SDK, a widely used software component in Bluetooth-enabled devices. The vulnerability could allow an attacker to gain unauthorized access to the RACE protocol, leading to a remote escalation of privilege<\/a>. This issue is particularly concerning because it does not require any additional execution privileges or user interaction to be exploited<\/a>. As a result, it poses a severe threat to devices using the affected audio SDK, potentially leading to system<\/a> compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-20702
\nSeverity: High (8.8 CVSS Severity Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Remote escalation of privilege<\/a> potentially leading to system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Airoha Bluetooth Audio<\/a> SDK | All versions prior to patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This vulnerability stems from insufficient security measures in the RACE<\/a> protocol of the Airoha Bluetooth audio SDK. An attacker could exploit<\/a> this flaw by sending specifically crafted data packets over the network to the targeted device. Upon receipt, the device processes these packets, enabling the attacker to manipulate the RACE protocol and escalate their privileges<\/a> remotely. The absence of required user interaction or additional execution privileges<\/a> makes this exploit remarkably stealthy and dangerous.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited. This example represents a malicious payload sent over the network to the targeted device.<\/p>\n

POST \/RACE\/protocol HTTP\/1.1\nHost: target_device_ip\nContent-Type: application\/bin\n{ \"malicious_payload\": \"base64_encoded_exploit_code\" }<\/code><\/pre>\n
In this simulated exploit, ‘base64_encoded_exploit_code’ would represent the actual malicious code designed to manipulate the RACE protocol and escalate privileges<\/a> on the targeted device.<\/p>\n
Mitigation<\/strong><\/p>\n
The best way to mitigate this vulnerability is to apply the vendor-provided patch for the Airoha Bluetooth<\/a> audio SDK. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method, providing an additional layer of security against potential exploitation<\/a>. Always remember that these are only temporary solutions, and applying the official patch should be the ultimate goal.<\/p>\n","protected":false},"excerpt":{"rendered":"
