CVE-2014-9585: Canonical Ubuntu Linux

Low severity, CVSS 2.1. EPSS: 0.6% chance of exploitation in the next 30 days.

The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD.
