Description

Bluetooth: bnep: fix wild-memory-access in proto_unregister

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

Bluetooth: bnep: fix wild-memory-access in proto_unregister

There's issue as follows:

KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f]

CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G W

RIP: 0010:proto_unregister+0xee/0x400

Call Trace:

<TASK>

__do_sys_delete_module+0x318/0x580

do_syscall_64+0xc1/0x1d0

entry_SYSCALL_64_after_hwframe+0x77/0x7f

As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init()

will cleanup all resource. Then when remove bnep module will call

bnep_sock_cleanup() to cleanup sock's resource.

To solve above issue just return bnep_sock_init()'s return value in

bnep_exit().
