Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ksmbd: close accepted socket when per-IP limit rejects connection<br />
<br />
When the per-IP connection limit is exceeded in ksmbd_kthread_fn(),<br />
the code sets ret = -EAGAIN and continues the accept loop without<br />
closing the just-accepted socket. That leaks one socket per rejected<br />
attempt from a single IP and enables a trivial remote DoS.<br />
<br />
Release client_sk before continuing.<br />
<br />
This bug was found with ZeroPath.
