About this tag
Bluetooth Mesh is a networking topology that allows many-to-many communication between Bluetooth devices, often used in IoT and smart-home gateways. On WindowsForum.com, discussions cover security vulnerabilities in Bluetooth Mesh implementations, such as CVE-2025-40284, a use-after-free bug in the Linux Bluetooth management stack that could crash systems when a mesh timer is not canceled after device removal.
