a13xp0p0v (me) posted an article about a few experiments with the pipe_buffer kernel object within his kernel-hack-drill project.

Alexander described multiple pipe_buffer features relevant for kernel exploits that rely on this object.
Alexander Popov Some notes on the security properties of the pipe_buffer kernel object Many exploits of Linux kernel vulnerabilities use the pipe_buffer kernel object to build strong exploit primitives. When I was experimenting with my personal project kernel-hack-drill, I discovered some interesting properties of pipe_buffer, which may not…
