On November 1, 2021, researchers publicly released a BrakTooth proof-of-concept (PoC) tool to test Bluetooth-enabled devices against potential Bluetooth exploits using the researcher’s software tools. BrakTooth—originally disclosed in August 2021—is a family of security vulnerabilities in commercial Bluetooth stacks. An attacker could exploit BrakTooth vulnerabilities to cause a range of effects from denial-of-service to arbitrary code execution.
CISA encourages manufacturers, vendors, and developers to review BRAKTOOTH: Causing Havoc on Bluetooth Link Manager and update vulnerable Bluetooth System-on-a-Chip (SoC) applications or apply appropriate workarounds.

CISA has issued Binding Operational Directive (BOD) 22-01, Reducing the Significant Risk of Known Exploited Vulnerabilities to addresses vulnerabilities that establishes specific timeframes for federal civilian agencies to remediate vulnerabilities that are being actively exploited by known adversaries. To support this Directive, CISA has established a catalog of relevant vulnerabilities. This catalog will be updated regularly, and organizations can sign up for notifications when new vulnerabilities are added. Â
CISA strongly recommends that private businesses, industry, and state, local, tribal and territorial (SLTT) governments prioritize mitigation of vulnerabilities in CISA’s Directive and sign up for updates to the catalog. Â
CISA urges organizations to review BOD 22-01 and the Fact Sheet for more information.
