CVE-2016-3672 (GCVE-0-2016-3672)

Vulnerability from cvelistv5 – Published: 2016-04-27 17:00 – Updated: 2024-08-06 00:03

Summary

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.

Severity ?

No CVSS data available.
