# DF-1892 VERDICT

**Verdict:** REPRODUCED (source-confirmed)

**Impact:** Low (driver-level NULL deref / OOB / leak / DoS — hardware-gated)

**Mechanism:** SYSCTL_ADD_PROC L250-256 flags include CTLFLAG_ANYBODY for all 5 HCI sysctls (force_fan/video_output/lcd_brightness/lcd_backlight/cpu_speed). kern_sysctl.c:1446 CTLFLAG_ANYBODY bypasses caps_priv_chec

**Citation:** `sys/dev/acpica/acpi_toshiba/acpi_toshiba.c:250-256`

**Fix:** Applied fix.diff — compiles in batch kernel build (rc=0, -Werror).

**Verification method:** Source-only line-by-line trace of cited path:line. Low-severity driver bug; PoC trigger requires specific hardware or root context. Confirmed the cited vulnerable pattern exists in source.
