kernel-rt is vulnerable to Denial of Service (DoS). The attack exists because it uses unsafe sprintf() in the Bluetooth implementation, creating a large number of Bluetooth L2CAP, SCO, or RFCOMM sockets could result in arbitrary memory pages being overwritten, allowing a local, unprivileged user to cause a denial of service or escalate their privileges.
