Android API Function Address Validation Vulnerability (CVE-2013-6282)
 Severity:    
 Advisory Date:  07 Jan 2014
The get_user and put_user API functions of the Linux kernel fail to validate the target address when being used on ARM v6k/v7 platforms. This functionality was originally implemented and controlled by the domain switching feature (CONFIG_CPU_USE_DOMAINS), which has been deprecated due to architectural changes. As a result, any kernel code using these API functions may introduce a security issue where none existed before. This allows an application to read and write kernel memory to, e.g., escalated privileges..
