What is Exploiting the Dirty COW Vulnerability about?

The document discusses the Dirty COW vulnerability, which is a race condition that existed in Linux kernel from 2007 to 2016. It allowed non-privileged users to gain root access by manipulating memory mappings of files like /etc/passwd. The vulnerability arises when a process maps readonly files to memory with MAP_PRIVATE, then a thread writes to the private copy while another discards it, modifying the original file. The document explains how attackers could exploit this by racing write and discard threads
