CVE-2024-50148

Summary

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().
