CISA's required action
What the flaw is
Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings.
CISA's description
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.
