CWE-ID: CWE-362
Exploitation vector: Remote access
Exploit availability: The vulnerability is being exploited in the wild
Vulnerable software:
Linux kernel
Software vendor:
Linux Foundation

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.


Remediation

Install update from vendor's website.
