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...
