CVE-2020-10135: Bluetooth Core

Medium severity, CVSS 5.4. EPSS: 2.4% chance of exploitation in the next 30 days.

Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key.

Affected products

• Opensuse Leap: version 15.1 only
