Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error within the hci_io_capa_request_evt() function in net/bluetooth/hci_event.c when handling HCI_EV_IO_CAPA_REQUEST packets. A remote attacker on the local network can force the system to assume that the remote peer does support SSP and potentially gain access to sensitive information.
