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.
This issue does not affect the versions of the kernel package as shipped with Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG 2.
