CVE-2020-10134

Pairing in Bluetooth® Core v5.2 and earlier may permit an unauthenticated
attacker to acquire credentials with two pairing devices via adjacent
access when the unauthenticated user initiates different pairing methods in
each peer device and an end-user erroneously completes both pairing
procedures with the MITM using the confirmation number of one peer as the
passkey of the other. An adjacent, unauthenticated attacker could be able
to initiate any Bluetooth operation on either attacked device exposed by
the enabled Bluetooth profiles. This exposure may be limited when the user
must authorize certain access explicitly, but so long as a user assumes
that it is the intended remote device requesting permissions, device-local
protections may be weakened.
