CVE-2016-0728 vulnerability has been found in the Linux kernel. When using it, a local user can attain root access permission. The issue has been there since 2012, and the worst part is that Android OS users are at the highest risk. The reason is Google doesn’t check apps created with NDK (Native Development Kit) and uploaded to Google Play.
As for PCs and servers, the situation is not so difficult, especially if the system has only one member. Also, the issue is not so dangerous if users are not allowed to execute code, or multiple instances of the operating system are in a virtualization environment. “
