CVE-2015-8964

Published: 16 November 2016

The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel before 4.5 allows local users to obtain sensitive information from kernel memory by reading a tty data structure.

From the Ubuntu security team

Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the TTY implementation in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
