The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through
3.14.3 does not properly manage tty driver access in the “LECHO & !OPOST”
case, which allows local users to cause a denial of service (memory
corruption and system crash) or gain privileges by triggering a race
condition involving read and write operations with long strings.
