# DF-1844 VERDICT

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

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

**Mechanism:** GPIOINFO handler L466-467 copyout(gp->pins,gpi->pins,sizeof(struct gpio_pin)*gp->npins) copies raw in-kernel struct array including trailing cdev_t dev field. struct gpio_pin gpio.h:77-85 {int pin_num

**Citation:** `sys/dev/misc/gpio/gpio.c:466-467`

**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.
