A flaw in the Airoha Bluetooth chip allowed attackers within range to spoof pairing requests and listen through Beats Studio Buds microphones before they were paired. Apple’s firmware update 1B211, rolled out automatically when the buds are near a paired iPhone, iPad, or Mac, patches the authentication issue.
- CVE-2025-20701: a Bluetooth pairing flaw in the Airoha chip used in Beats Studio Buds let nearby attackers spoof pairing and access the mic before pairing completed.
- Chaining this bug with other Airoha SoC weaknesses could let attackers steal Bluetooth keys, impersonate trusted headphones, hijack calls, or trigger the voice assistant.
- Exploitation requires custom hardware, specialized software, and close range, so it mainly threatens targeted individuals like stalking victims or high-value targets, not casual eavesdroppers.
- Apple's firmware update 1B211 fixes the issue and installs automatically when the buds stay in their case near a charged, paired iPhone, iPad, or Mac—verify via Settings > Bluetooth info icon.
