flaw to bypass the Address Space Layout Randomization (ASLR) protection
mechanism. (CVE-2015-1593)
An information leak was discovered in the Linux Kernel's handling of
userspace configuration of the link layer control (LLC). A local user could
exploit this flaw to read data from other sysctl settings. (CVE-2015-2041)
