In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: bnep: pin L2CAP connection during netdev registration

bnep_add_connection() reads the L2CAP connection without holding the

channel lock, then passes its HCI device to register_netdev(). Controller

teardown can clear and release that connection concurrently, leaving the

network device registration path to dereference a freed parent device.

Take a reference to the L2CAP connection while holding the channel lock.

Retain it until register_netdev() has taken the parent device reference. (NVD)
