CVE-2020-26555

Published: 24 May 2021

Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B through 5.2 may permit an unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without knowledge of the PIN.

From the Ubuntu security team

It was discovered that the BR/EDR pin-code pairing procedure in the Linux kernel was vulnerable to an impersonation attack. A physically proximate attacker could possibly use this to pair to a device without knowledge of the pin-code.

Priority

Medium
