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

vt: stabilize tty reference in kbd_keycode with tty_port_tty_get

kbd_keycode() reads vc->port.tty without acquiring a tty reference,

racing against con_shutdown() which clears port.tty under a different

lock. Use tty_port_tty_get()/tty_kref_put() to hold a proper reference

for the duration the tty pointer is needed. (NVD)
