BLUETOOTH HEADPHONE JACKING: FULL DISCLOSURE OF AIROHA RACE VULNERABILITIES

Summary from the TLDR InfoSec newsletter

Researchers discovered a series of vulnerabilities in the Airoha Bluetooth SoCs used in many true wireless earbuds, including those from Sony, Bose, and Marshall. The vulnerabilities include a lack of authentication when connecting a device over Bluetooth Classic or BLE, as well as the devices implementing a custom protocol, called RACE, which allows for reading and writing RAM. An attacker could chain these vulnerabilities to impersonate a user's headphones and then issue commands via a device's virtual assistant or eavesdrop on calls.
