   This kernel live patch for Linux Kernel 3.12.49-11.1 fixes three security

   - CVE-2016-0728: A reference leak in keyring handling with
     join_session_keyring() could lead to local attackers gain root
     privileges. (bsc#962078).
   - CVE-2015-8660: The ovl_setattr 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/af_unix.c in the

     calls. (bsc#955837)
