Unseen Threat in Your Ears: A Security Crisis in Premium Audio Gear
In a chilling wake-up call for millions of users worldwide, cybersecurity experts have uncovered major security flaws in a wide range of Bluetooth headphones and earbuds powered by Airoha Systems-on-Chip (SoCs). These vulnerabilities allow attackers within just 10 meters to compromise affected devices without even needing authentication. This means that brands long trusted for high-quality audio — including Sony, Bose, Marshall, and Jabra — may unknowingly be putting users at risk. From eavesdropping on private conversations to full device takeover, these flaws are more than a technical hiccup; they represent a systemic vulnerability in the modern consumer electronics supply chain. And because many vendors don’t even realize their products include Airoha chips, the true scope of exposure may still be hidden.
Hidden Dangers Behind Premium Headphones
Security researchers have revealed that Bluetooth headphones and earbuds using Airoha SoCs contain serious vulnerabilities that can be exploited by hackers within Bluetooth range. The flaws do not require full authentication, making them a prime opportunity for malicious attacks. Affected products span across major consumer brands such as Sony, Bose, Marshall, and Jabra, placing millions of users at risk of privacy breaches and data theft.
Three distinct CVEs have been identified as the entry points for these attacks: CVE-2025-20700, CVE-2025-20701, and CVE-2025-20702. These involve missing GATT service authentication, unauthenticated access through BR/EDR Bluetooth protocols, and unsecured custom communication channels. Collectively, these weaknesses allow attackers to access and manipulate RAM or flash memory, extract Bluetooth link keys to impersonate trusted devices, hijack microphones, redirect calls, and even steal media playback data, contact information, and call history.
What’s especially alarming is the wormable potential of these exploits. Attackers can rewrite firmware on compromised devices, enabling malicious code to spread to other connected systems. This turns the vulnerability from a point-target issue into a propagating cyber threat. Devices tested include popular high-end models like the Sony WH-1000XM6 and WF-1000XM5, Marshall’s MAJOR V, Bose QuietComfort Earbuds, and Jabra’s Elite 8 Active.
Airoha released a patched SDK to manufacturers in early June 2025. However, no firmware updates have yet reached consumers, leaving many users unknowingly vulnerable. Security experts advise high-risk individuals, such as journalists or diplomats, to immediately stop using the affected devices, remove Bluetooth pairings, and monitor manufacturer websites for updates.
The vulnerability disclosure timeline shows a sluggish response from Airoha. The initial report was made on March 25, 2025, but the company did not respond until May 27. The SDK patch only became available to vendors by June 4, and a public advisory was finally issued on June 26. This delay underscores the critical need for improved transparency and responsiveness in IoT supply chains.
These revelations expose deeper, systemic issues within the tech ecosystem, especially when manufacturers rely on third-party components without full awareness of their architecture. The flaws don’t just pose a privacy risk — they’re a warning about how easily overlooked hardware dependencies can unravel entire networks of trust in modern consumer devices.
What Undercode Say:
A Growing Problem in Silent Hardware Dependencies
At the heart of this issue lies a problem that’s becoming increasingly common in the consumer tech industry: supply chain opacity. Vendors often integrate third-party chipsets and modules into their products without fully understanding their security architecture. In this case, several high-profile brands appear unaware that their Bluetooth headphones and earbuds even used Airoha SoCs. This lack of visibility makes coordinated responses to threats slow, inefficient, or entirely impossible.
Bluetooth’s Double-Edged Sword
Bluetooth technology has long promised seamless connectivity, but that convenience comes with a cost. The vulnerabilities identified in Airoha chips reveal that low-level protocols like BLE GATT and RFCOMM can be abused in sophisticated ways. The fact that attackers can access RAM and flash memory, steal link keys, and eavesdrop on calls through microphone hijacking turns a friendly headphone into a dangerous surveillance device.
Wormable Potential Raises Red Flags
What’s even more concerning is the potential for wormable exploits. If attackers can rewrite firmware to propagate malware, we’re no longer dealing with isolated attacks but with large-scale infection vectors. This brings to mind other infamous vulnerabilities like BlueBorne or KRACK, but the consumer-centric nature of headphones and earbuds makes this threat more immediate and intimate — especially as these are products people use daily, often in private or sensitive environments.
Inadequate Response Timeline
The disclosure timeline shows a three-month delay between initial notification and the release of an SDK patch. For something affecting global brands and millions of consumers, that’s far too long. Airoha’s initial silence and the delayed reaction suggest systemic problems in how security is prioritized in chip manufacturing. The fact that patches are still not in users’ hands further highlights the disconnect between the manufacturer and end-user protection.
Real-World Implications
The affected models include some of the most widely sold and reviewed devices on the market. The Sony WH-1000XM series, for example, has been touted as industry-leading for years. To learn that such products may have backdoors into a user’s conversations or contact history is not just unsettling — it damages trust in entire product lines and brands.
IoT Ecosystem Trust Is Crumbling
This incident illustrates how deeply embedded trust has become fragile in the Internet of Things (IoT) ecosystem. From the consumer’s perspective, it’s not always clear where hardware comes from or what protocols it uses. Manufacturers need to be more transparent about their component choices and more proactive in distributing updates when vulnerabilities arise.
Users Left Holding the Bag
Despite a fix being available, users have no current way to secure their devices unless manufacturers rapidly release updated firmware. Until then, the only safe solution is to stop using the affected headphones. For professionals who depend on privacy — like diplomats, journalists, or lawyers — this could mean abandoning expensive gear due to a hidden flaw.
