Description Prasad J Pandit 2014-02-20 11:13:00 EST
Linux kernel built for the s390 architecture(CONFIG_S390) is vulnerable to a
crash due to low-address protection exception. It occurs when an application
uses a linkage stack instruction.

An unprivileged user/application could use this flaw to crash the system
resulting in DoS.
