Title: Vulnerabilities in BrakTooth Bluetooth
description: Recently, security researchers revealed details of a large number of security vulnerabilities affecting the delivery of the Bluetooth software stack.
What does BrakTooth affect?
BrakTooth affects leading SoC vendors including Qualcomm, Intel, Texas Instruments, Silicon Labs, and Infineon (Cypress), and more. Chips that are susceptible are believed to be used by Microsoft Surface laptops, many Qualcomm-based smartphone models, and Dell laptops.
What causes this vulnerability?
It turns out that some devices can crash by sending prepared LMP packets and recovered after a simple restart. Other devices may allow an attacker to run malicious code on vulnerable devices via BLMP packets. These packages are used by Bluetooth to set up and configure links with other devices.
What do the researchers say? What is their opinion?
The researchers note that all 11 vendors were made aware of potential security issues a few months ago, and even before the findings were published. Bluetrum, Infineon and Expressif have also released their patches. Upon receipt of the necessary information, other vendors confirmed these findings but did not confirm a specific security patch release date.
However, we learned that Texas Instruments has stated that it will not address bugs that affect their chipsets.
We remind you that the BrakTooth vulnerability is based on the Bluetooth Classic protocol, the attacker must be within the target's radio range, so make sure you turn on Bluetooth only in safe environments. It is very important .
