FKIE_CVE-2014-0196

Vulnerability from fkie_nvd - Published: 2014-05-07 10:55 - Updated: 2026-06-17 00:02
Summary
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.
