Subscribe to Bluetooth Core Specification

Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 up to and including 5.2 may permit a nearby man-in-the-middle malicious user to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this malicious user to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.

Several vulnerabilities were discovered in Bluez, the Linux Bluetooth protocol stack CVE-2020-26558 / CVE-2021-0129 It was discovered that Bluez does not properly check permissions during pairing operation, which could allow an attacker to impersonate the initiating device CVE-2020-27153 Jay LV discovered a double free flaw in th ...

Several security issues were fixed in the Linux kernel ...

A vulnerability was found in Linux Kernel, where Passkey Entry protocol used in Secure Simple Pairing (SSP), Secure Connections (SC) and LE Secure Connections (LESC) of the Bluetooth Core Specification is vulnerable to an impersonation attack where an active attacker can impersonate the initiating device without any previous knowledge ...
