    CVE-2014-9585

    Published: 9 Jan 2015Last Modified: 16 Apr 2026

    Summary:

    Details: 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.
