Wireless Vulnerabilities Escalate at Unprecedented Rate, Doubling Every Few Years

A recent threat report from Bastille Networks, based on data from the NIST National Vulnerability Database, reveals a staggering surge in wireless vulnerabilities. In 2025, researchers disclosed 937 new wireless-related CVEs, averaging 2.5 per day.

Surge in Wireless Vulnerabilities

This represents a 20-fold increase in growth rate compared to the broader CVE field. The wireless CVE category has expanded dramatically, from just 4 disclosures in 2010 to 932 in 2025, a 230-fold increase.

Wireless Disclosures on the Rise

Wireless disclosures now account for nearly 2% of all annual CVE disclosures. Annual growth rates for wireless CVEs have consistently exceeded 25% since 2016, with a peak of 56% in 2017. The cumulative total has doubled every two to four years since 2014.

Wi-Fi and Bluetooth Dominance

Wi-Fi and Bluetooth account for the majority of wireless CVEs, with Wi-Fi being the dominant contributor. By 2025, Wi-Fi accounted for approximately 60% of wireless disclosures. Bluetooth is the second-largest category, with its prevalence across mobile, medical, automotive, and IoT devices making its growth operationally significant.

Cellular Vulnerabilities

Cellular vulnerabilities, covering LTE and 5G, remain lower in raw count, but may be structurally underreported due to the complexity of baseband processors and the opacity of carrier firmware.

High-Profile Vulnerabilities

Several high-profile vulnerabilities disclosed in 2025 highlight the systemic nature of wireless exposure. The WhisperPair vulnerability (CVE-2025-36911) allows an attacker to force wireless audio accessories to pair without user interaction. Memory corruption flaws in MediaTek WLAN drivers (CVE-2025-20631, 20632, and 20633) can enable privilege escalation and remote code execution. An uncaught exception in MediaTek 5G modem firmware (CVE-2025-20753) can cause the modem to crash and disrupt connectivity.

Patching Constraints

Patching constraints extend exposure windows, as many affected devices cannot be patched or receive firmware updates on standard enterprise timelines. IoT sensors, SCADA equipment, and embedded industrial controllers often lack centralized patch management mechanisms.

Emerging Threats

The use of machine learning and AI-assisted attacks is an emerging factor, as attackers can train models on RF telemetry and device fingerprints to prioritize environments with dense Bluetooth peripheral usage or exposed Wi-Fi infrastructure. Nation-state actors are likely to integrate AI-driven analytics with custom wireless tooling for persistent reconnaissance against government facilities, defense contractors, and critical infrastructure.

Recommendations

Traditional vulnerability management controls often fail to detect personal Bluetooth peripherals, embedded Zigbee systems, transient third-party wireless equipment, or cellular-connected devices operating outside enterprise network boundaries. To address this visibility gap, Bastille recommends continuous passive monitoring of the wireless radio frequency environment and integrating wireless data into existing vulnerability management and incident response workflows.

According to Chris Risley, CEO at Bastille Networks, “Wireless threats are proliferating, and this report highlights the alarming extent to which that is the case, as well as the theft and espionage risks companies and governments face. Anything that can be controlled wirelessly is vulnerable. With the explosion of new AI data centers and other high-value targets worth billions of dollars in intellectual property or trade secrets, now is the time for enterprises to start treating wireless visibility and vulnerability management as foundational security infrastructure.”
