Executive Summary

CVE-2026-16101 is a Bluetooth Low Energy (BLE) re-pairing vulnerability affecting Silicon Labs SiWx91x and RS9116W devices. An attacker can spoof a bonded device to force a re-pairing process with a rogue device, potentially allowing unauthorized access or data interception.

Impact Analysis

This vulnerability enables impersonation and Man-in-the-Middle attacks. Attackers could intercept or manipulate BLE communications, leading to unauthorized access to sensitive data or control of paired devices. The impact includes potential data breaches or device hijacking.

Mitigation Strategies

Update the Silicon Labs SiWx91x Bluetooth LE SDK to version 4.1.0 or later. Use the rsi_ble_vendor_set_SMP_min_enc_keysize API to enforce minimum encryption key sizes between 7 and 16 bytes during BLE pairing processes.
