kernel: ASLR bruteforce possible for vdso library
Published Jan 9, 2015
2.1
LOWCVSS 2.0
EPSS 0.56%
Description
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.
