[Impact]
 Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did
 not properly perform permissions checks when handling HCI sockets. A
 physically proximate attacker could use this to cause a denial of service
 (bluetooth communication).

[Potential regression]
Bluetooth users may be affected.

Ruihan Li (1):
  bluetooth: Perform careful capability checks in hci_sock_ioctl()
