| In the Linux Kernel 'ring (0)' a stack is also allocated for local variables defined in functions. These functions are mainly implemented for device drivers that are defined in different Loadable Kernel Modules (LKMs). The same stack is also vulnerable to stack overflow attacks that aim at overwriting the return address saved on the stack - this post will cover exploiting these vulnerabilities.
