What it is

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

ksmbd: close accepted socket when per-IP limit rejects connection

When the per-IP connection limit is exceeded in ksmbd_kthread_fn(),

the code sets ret = -EAGAIN and continues the accept loop without

closing the just-accepted socket. That leaks one socket per rejected

attempt from a single IP and enables a trivial remote DoS.

Release client_sk before continuing.

This bug was found with ZeroPath.
