From Collision To Exploitation:Unleashing Use-After-Free Vulnerabilities in Linux Kernel


This paper was published in CCS 2015. With the introduction of the various mitigation deployed in the user space, especially sandbox, the vulnerability in the linux kernel has become a target of the attacker. However, the memory space in the kernel is hard to predict since the kernel space are used by various tasks. In this paper, the author introduces a much stabler way to put desired vulnerable target into kernel memory space by exploiting a use-after-free in linux kernel.
