This issue was patched in ALAS-2013-233.

NVD Description

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

The do_tkill function in kernel/signal.c in the Linux kernel before 3.8.9 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted application that makes a (1) tkill or (2) tgkill system call.
