Description

Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ. A heap buffer overflow flaw was found in the way the Linux kernel’s Bluetooth implementation processed extended advertising report events. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or to potentially execute arbitrary code on the system by sending a specially crafted Bluetooth packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
