Description

Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access. A flaw was found in the way the Linux kernel’s Bluetooth implementation handled L2CAP (Logical Link Control and Adaptation Protocol) packets with A2MP (Alternate MAC-PHY Manager Protocol) CID (Channel Identifier). This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
