CVE-2013-6282

Status Candidate

Overview

The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.

Android get_user/put_user Exploit
Posted Dec 26, 2016
Authored by timwr, fi01, cubeundcube | Site metasploit.com

This Metasploit module exploits a missing check in the get_user and put_user API functions in the linux kernel before 3.5.5. The missing checks on these functions allow an unprivileged user to read and write kernel memory. This exploit first reads the kernel memory to identify the commit_creds and ptmx_fops address, then uses the write primitive to execute shellcode as uid 0. The exploit was first discovered in the wild in the vroot rooting application.
