CVE-2014-2039 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2039):

arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle 
attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) 
by executing a crafted instruction.
