Re: How about importing yara into kernel space ?

Not entirely true. The YARA VM does not run native instructions directly, so if you did manage to jump somewhere other than YARA instructions the VM would likely crash badly. If this can lead to arbitrary code execution, I have no idea. Jumps are not bad. BPF, which runs in the kernel, allows
