Bluetooth: L2CAP: Fix uaf in l2cap_connect

...

The vulnerability of the l2cap_sock_recv_cb() function in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the l2capsockrecvcb function in the net/bluetooth/l2capsock.c module of the Linux kernel is related to pointer arithmetic errors. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected information...
