CVE-2020-12351, also known as BleedingTooth, is a type-confusion vulnerability in the Linux kernel Bluetooth implementation. Improper handling of L2CAP packets carrying an A2MP (Alternate MAC-PHY Manager Protocol) channel identifier permits incompatible object types to be processed. An unauthenticated attacker in Bluetooth range can transmit a specially crafted L2CAP packet to trigger the flaw without user interaction. The issue affects vulnerable Linux and BlueZ-based deployments, including affected Red Hat Enterprise Linux 7 and 8 kernel builds.
