Flipping Pages: An analysis of a new Linux vulnerability in nf_tables and hardened exploitation techniques
A tale about exploiting KernelCTF Mitigation, Debian, and Ubuntu instances with a double-free in nf_tables in the Linux kernel, using novel techniques like Dirty Pagedirectory. All without even having to recompile the exploit for different kernel targets once.
