CRITICAL 9.1

DescriptionCVE.org

An issue was discovered in COROS PACE 3 through 3.0808.0. Due to an out-of-bounds read vulnerability, sending a crafted BLE message forces the device to reboot.

Executive ViewAI

Why It Matters

COROS PACE 3 smartwatch users face a critical denial-of-service vulnerability that forces device reboots via malicious Bluetooth messages, with no vendor patch currently available. Organizations deploying these devices for employee fitness tracking or health monitoring should assess exposure and implement interim protective measures to prevent disruption to business operations and user productivity.

Business Impact: High

Compensating Controls

Restrict Bluetooth connectivity to trusted, enterprise-managed devices only; disable BLE advertisement scanning in non-work environments; implement network segmentation to isolate IoT/wearable traffic; monitor for repeated device reboots as indicator of exploitation; consider disabling non-essential smartwatch features until patch release; educate users to avoid pairing with unknown Bluetooth devices.

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
