FreeBSoD: Leveraging Language Models to Find and Exploit Kernel Bugs (Part 2 of 2)

KASLR randomizes the kernel’s base address at boot, so hardcoded offsets to kernel symbols like prison0, rootvnode, or ROP gadgets won’t work without first leaking a kernel text pointer.

FreeBSD does not implement KASLR. FreeBSD implements many features reachable via an unprivileged process that can be considered information leaks, leaking kernel stack, heap, and text addresses (pretty much everything.) For a very simple demonstration: sysctl -a | grep 0xf. Also look at the sysctl nodes that the gpart(8) program uses.
