    CVE-2014-3534

    arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.
