In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: u_serial: Add null pointer check in gserial_resume
Consider a case where gserial_disconnect has already cleared
gser->ioport. And if a wakeup interrupt triggers afterwards,
gserial_resume gets called, which will lead to accessing of
gser->ioport and thus causing null pointer dereference.Add
a null pointer check to prevent this.
Added a static spinlock to prevent gser->ioport from becoming
null after the newly added check.
