NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

The load_script function in fs/binfmt_script.c in the Linux kernel before 3.7.2 does not properly handle recursion, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.
