CVE-2016-3672 | BDVDB-2026-75566 Detail
Description#
The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel 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.
Impact#
No impact statement in the source data.
Weaknesses#
No weakness recorded in the source data.
