Overview

  • ERNW researchers discovered the Bluetooth chip flaw in March and revealed it publicly on June 26 after Airoha supplied patched SDKs on June 4.
  • The vulnerability lies in Airoha’s proprietary Bluetooth SoCs embedded in over 100 headphone models from Sony, JBL, Bose, Marshall and others.
  • Exploits allow nearby attackers to read data from chip memory, hijack calls or trigger voice assistants without pairing.
  • Airoha delivered updated development kits to manufacturers but no firmware patches have been issued to consumers as of June 27.
  • Apple’s AirPods are exempt from the flaw, and three CVE identifiers (CVE-2025-20700 through CVE-2025-20702) carry disputed severity ratings between ERNW and Airoha.
