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, dfbsd-qemu/vm.sh, snapshot 'with-src' baseline)
Kernel source: /usr/src/sys == sys/ tree of this audit (usb_process.c
        sha256 verified equal to repo copy before patching)
Compiler: gcc80 (CCVER=gcc80), DragonFly nativekernel flow
Module build: KLD via bsd.kmod.mk (make in /root/dfharness)
USB state: device usb compiled in (X86_64_GENERIC); harness drives the
        production usb_proc_* kernel symbols directly — no USB hardware
        needed (evidence class: production-code KLD harness, as the
        DF-5367..DF-5504 family rigs)
sysctl hw.usb.debug: 0
Note: guest runs WITHOUT SMAP/SMEP/KASLR (intentionally permissive
        audit target) — irrelevant here, findings are logic/DoS class.
