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.

CVE-2014-9585 [LOW] CVE-2014-9585 kernel: ASLR bruteforce possible for vdso library
CVE-2014-9585 kernel: ASLR bruteforce possible for vdso library
Linux kernel built with the Virtual Dynamic Shared Object(vDSO) support is
vulnerable to an information leakage flaw. It occurs due to less than perfect
address randomisation, which leads to leakage of vDSO library base address.
An unprivileged user could use this flaw to leak kernel memory addresses.
