And if gserial_suspend gets called afterwards, it will lead to accessing of gser-&gt;ioport and thus causing null pointer dereference.</p> <p>Avoid this by adding a null pointer check. Added a static spinlock to prevent gser-&gt;ioport from becoming null after the newly added null pointer check.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>usb: gadget: u_serial: Add null pointer check in gserial_suspend</p> <p>Consider a case where gserial_disconnect has already cleared gser-&gt;ioport.
