Guest: DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul 2 06:02:54 UTC 2026 root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64 QEMU/KVM single-tenant audit guest (dfbsd-qemu/vm.sh). Hardware presence check (2026-09-19): pciconf -lv | grep -ci "winbond|w89c840|compex" -> 0 (no W89C840F/RL100-ATX NIC) /boot/kernel/if_wb.ko -> exists (built, not loaded) kldstat | grep -c "drm|wb" -> 0 (no amdgpu/DCN1 GPU) Conclusion: the audited device classes are absent from the guest; kernel-level PoC execution is impossible for these findings. Verification is source-level (logic harnesses compiled with the guest's own cc where applicable).
