    The PS4 4.55/FreeBSD BPF kernel exploit writeup is now up on my GitHub repo! The bug is present on any system running FreeBSD such that you have privileges (which we did on PS4). Could be used on other systems for root to ring0 code execution.https://github.com/Cryptogenic/Exploit-Writeups/blob/master/FreeBSD/PS4%204.55%20BPF%20Race%20Condition%20Kernel%20Exploit%20Writeup.md …

        It could be useful as a root to ring0 privilege escalation, but it's not as nice as on a system like the PS4 where you go from completely untrusted to ring0.

        Wasn't this fixed over 5 years ago in FreeBSD, though? With https://svnweb.freebsd.org/base/head/sys/net/bpf.c?revision=236262&view=markup#l1762 … can it still be a use-after-free?
