Description

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.

In plain language

AI Worth attention

CVE-2025-20700 is a Bluetooth software permission bypass in Airoha’s Bluetooth audio SDK that could let an attacker access sensitive “RACE protocol” data and potentially gain higher control remotely; small businesses should act if they use products built on affected Airoha Bluetooth audio SDKs.

What to do

  1. Contact your device/vendor or integrator and ask for a firmware update that fixes CVE-2025-20700 for the Airoha Bluetooth audio SDK used in your product.
  2. Inventory your deployed Bluetooth devices that use Airoha AB156x/AB157x/AB158x/AB159x/AB1627-based components, and flag any models that can be updated.
  3. If you can’t get a fix quickly, reduce Bluetooth exposure in your environment (for example, limit device pairing/availability where practical) and monitor for vendor guidance.
