CVE-2022-25837

Bluetooth® Pairing in Bluetooth Core Specification v1.0B through v5.3 may
permit an unauthenticated MITM to acquire credentials with two pairing
devices via adjacent access when at least one device supports BR/EDR Secure
Connections pairing and the other BR/EDR Legacy PIN code pairing if the
MITM negotiates BR/EDR Secure Simple Pairing in Secure Connections mode
using the Passkey association model with the pairing Initiator and BR/EDR
Legacy PIN code pairing with the pairing Responder and brute forces the
Passkey entered by the user into the Responder as a 6-digit PIN code. The
MITM attacker can use the identified PIN code value as the Passkey value to
complete authentication with the Initiator via Bluetooth pairing method
confusion.
