CVE-2016-3672

CVE Details

Release Date:	2018-07-30
Impact:	None	What is this?

Description

The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linuxkernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits.
