CVE-2025-20702
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Airoha Bluetooth audio SDK, there is a possible unauthorized access to the RACE protocol. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Airoha Bluetooth audio SDK contains a vulnerability where the RACE (Radio Access Control Engineering) protocol can be accessed without proper authorization. This allows an attacker to achieve remote privilege escalation by sending specially crafted commands to the RACE interface, potentially executing privileged operations or accessing sensitive functions without authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Airoha Bluetooth audio SDK usageDetermine if your product or firmware uses the Airoha Bluetooth audio SDK. Check firmware BOM, SDK documentation, or library dependencies for Airoha components.Affected if Your device firmware or software explicitly includes Airoha Bluetooth audio SDK components.
-
Locate RACE protocol interfaceSearch firmware image or SDK files for RACE-related binaries, services, or network ports. Common indicators: 'race', 'RACE daemon', or port configurations used by RACE protocol (consult SDK documentation for specific file names or paths).Affected if RACE protocol binaries, services, or listening ports are present in the firmware or SDK deployment.
-
Verify RACE protocol is enabledCheck configuration files, build settings, or runtime flags that control RACE functionality. Look for settings that enable/disable RACE daemon or interface access.Affected if RACE protocol is enabled or accessible in the current firmware configuration.
-
Inspect RACE authentication mechanismExamine SDK source code or firmware disassembly for authentication checks before RACE command processing. Look for functions that validate user credentials or session tokens before allowing privileged operations.Affected if No authentication or authorization check is performed before executing RACE commands, or the check is missing/disabled.
You are affected if your device runs an Airoha Bluetooth audio SDK with the RACE protocol enabled and accessible without proper authentication checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict access to the RACE protocol by implementing proper authentication and authorization checks, or disable RACE functionality in production firmware builds. Update to SDK versions that secure RACE protocol access.
