  "details": "In the Linux kernel, the following vulnerability has been resolved:  tty: port: fix tty_port_tty_vhangup() race  Drivers rely on tty_port_tty_vhangup() to synchronously hang up their ports before tearing down resources as part of deregistration (e.g. on physical disconnect).  If tty_port_tty_vhangup() races with another hangup it may however return before the port has been shut down. This is in turn can lead to use-after-free and NULL-pointer dereferences in racing ioctls (including a synchronous hangup) and in processing of racing asynchronous hangups (carrier loss).  Add the missing serialisation to tty_port_tty_vhangup() and tty_port_hangup() so that the former does not return until the port has been shut down also when there is a racing hangup.  Note that serial core does not use tty_port_hangup(), but it already holds the port mutex when clearing port-\u003etty and shutting down the port in uart_hangup().",
