Texas Instruments said they would not be addressing the flaws impacting their chipsets.

Despite having received the necessary information, the other vendors acknowledged the researchers’ findings but could not confirm a definite release date for a security patch, citing internal investigations into how each of the BrakTooth bugs impacted their software stacks and product portfolios. The researchers claim that all 11 vendors were notified about these security issues months ago (more than 90 days), well before they published their findings.Įxpressif ( pdf), Infineon, and Bluetrum have released patches. Researchers believe the number of affected devices could be in the billions.įull technical details and explanations for all 16 vulnerabilities can be found on the dedicated BrakTooth website where they are numbered V1 – V16 along with the associated CVEs.

Others can allow a remote attacker to run malicious code on vulnerable devices via Bluetooth Link Manager Protocol (LMP) packets-the protocol Bluetooth uses to set up and configure links to other devices. Some can be crashed by sending specially crafted LMP packets, which can be cured with a simple restart. It needs to be said that the impact is not the same for every type of device. However, looking further, they found that the same Bluetooth firmware was most likely used inside more than 1,400 chipsets, used as the base for a wide range of devices, such as laptops, smartphones, industrial equipment, and many types of smart “Internet of Things” devices. However, the researchers say they only examined the Bluetooth software libraries for 13 SoC boards from 11 vendors. Vulnerable chips are used by Microsoft Surface laptops, Dell desktops, and several Qualcomm-based smartphone models. They decided to dub this set of vulnerabilities BrakTooth.īrakTooth affects major SoC providers such as Intel, Qualcomm, Texas Instruments, Infineon (Cypress), Silicon Labs and others. The same group of researchers disclosed the SweynTooth vulnerabilities in February 2020. Security researchers have revealed details about a set of 16 vulnerabilities that impact the Bluetooth software stack that ships with System-on-Chip (SoC) boards from several popular vendors.
