Silicon Labs Bluetooth Low Energy SDK before 2.13.3 has a buffer overflow via packet data. This is an over-the-air remote code execution vulnerability in Bluetooth LE in EFR32 SoCs and associated modules running Bluetooth SDK, supporting Central or Observer roles.

Use After Free vulnerability in Silicon Labs Bluetooth SDK on 32 bit, ARM may allow an attacker with precise timing capabilities to intercept a small number of packets intended for a recipient that has left the network.This issue affects Silabs Bluetooth SDK: through 8.0.0.

A memory leak in the EFR32 Bluetooth LE stack 5.1.0 through 5.1.1 allows an attacker to send an invalid pairing message and cause future legitimate connection attempts to fail. A reset of the device immediately clears the error.

Silicon Labs Bluetooth Low Energy SDK before 2.13.3 has a buffer overflow via packet data. This is an over-the-air denial of service vulnerability in Bluetooth LE in EFR32 SoCs and associated modules running Bluetooth SDK, supporting Central or Observer roles.
