This kernel live patch for Linux Kernel 3.12.51-60.20.2 fixes three security issues:
Fixes: - CVE-2016-0728: A reference leak in keyring handling with joinsessionkeyring() could lead to local attackers gain root privileges. (bsc#962078). - CVE-2015-8660: The ovlsetattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application. (bsc#960329) - CVE-2013-7446: Use-after-free vulnerability in net/unix/afunix.c in the Linux kernel allowed local users to bypass intended AFUNIX socket permissions or cause a denial of service (panic) via crafted epollctl calls. (bsc#955837)
