tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup
In the Linux kernel, the following vulnerability has been resolved: tty: vcc: hold port lock when clearing tty pointer in vcc_cleanup vcc_cleanup() sets port->tty to NULL without holding port->lock, racing with vcc_event() LDC callbacks that read port->tty under port->lock and then use tty->port. This can cause a use-after-free when the callback dereferences tty->port after cleanup has already destroyed and freed it.
