NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-kdump-devel package and not the kernel-kdump-devel package as distributed by RHEL.
See How to fix? for RHEL:6 relevant fixed versions and status.
The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call.
