CVE-2015-3332 Linux kernel vulnerability
Title: Linux kernel vulnerability
Summary: The system could be made to crash under certain conditions.
A flaw was discovered in the Linux kernel's IPv4 networking when using TCP
fast open to initiate a connection. An unprivileged local user could
exploit this flaw to cause a denial of service (system crash).
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.

CVE-2015-3332 [MEDIUM] CVE-2015-3332 kernel: TCP Fast Open local DoS
CVE-2015-3332 kernel: TCP Fast Open local DoS
Linux kernel built with the IPv4 networking support(CONFIG_NET) is vulnerable to a DoS flaw. It could occur while using TCP Fast open option when initiating a network connection. This issue is a regression caused by upstream commit '355a901e6cf1', when it was back-ported to older 3.10.y - 3.16.y branches.
An unprivileged local user could use this flaw to crash the system resulting in DoS.
