AI-analyzed exploit summary This repository contains a functional proof-of-concept exploit for CVE-2015-6640, a Linux kernel vulnerability related to the PR_SET_VMA prctl operation. The exploit demonstrates the vulnerability by manipulating memory mappings and verifying the behavior via /proc/self/maps.

Description

The prctl_set_vma_anon_name function in kernel/sys.c in Android before 5.1.1 LMY49F and 6.0 before 2016-01-01 does not ensure that only one vma is accessed in a certain update action, which allows attackers to gain privileges or cause a denial of service (vma list corruption) via a crafted application, aka internal bug 20017123.
