Cross Transport Key Derivation in Bluetooth Core Specification v4.2 and v5.0 may permit an unauthenticated user to establish a bonding with one transport, either LE or BR/EDR, and replace a bonding already established on the opposing transport, BR/EDR or LE, potentially overwriting an authenticated key with an unauthenticated key, or a key with greater entropy with one with less."

Cross Transport Key Derivation en Bluetooth Core Specification versiones v4.2 y v5.0, puede permitir a un usuario no autenticado establecer una vinculaci\u00f3n con un transporte, ya sea LE o BR/EDR, y reemplazar una vinculaci\u00f3n ya establecida en el transporte opuesto, BR/EDR o LE, potencialmente sobrescribiendo una clave autenticada con una clave no autenticada, o una clave con mayor entrop\u00eda con una con menos"
