kernel: tty: add the option to have a tty reject a new ldisc

A vulnerability was found in the Linux kernel's TTY subsystem, where the option to reject a new ldisc was improperly implemented, which can lead to a situation where the conwrite routine is called while holding a spinlock, potentially causing a sleep operation in an invalid context...

The vulnerability of the tty_buffer component in the Linux operating system’s kernel allows a hacker to cause a service failure.

The vulnerability of the ttybuffer component in the Linux operating system’s kernel is related to improper blocking in the flushtoldisc function. Exploiting this vulnerability can allow an attacker to cause a service failure...
