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. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. Actively exploited in the wild (cisa kev) and public exploit code available.
