NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-devel package and not the kernel-debug-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h.
