Linux Kernel is vulnerable to a denial of service, caused by a NULL pointer dereference flaw in the sco_sock_getsockopt function in net/bluetooth/sco.c. By sending a specially-crafted request using BT_SNDMTU/BT_RCVMTU for SCO sockets, a local authenticated attacker could exploit this vulnerability to cause the system to crash or kernel internal information.
