On Audi A7 MMI 2014 vehicles, the Bluetooth stack in Audi A7 MMI Multiplayer with version (N+R_CN_AU_P0395) mishandles %x and %s format string specifiers in a device name. This may lead to memory content leaks and potentially crash the services.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
