# DF-1631 VERDICT

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

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

**Mechanism:** evdev.c/cdev.c:118 client kmalloc before device lock. Error paths: si_drv1 NULL race (133), evdev_register_client fail (136, ev_open callback error at 990), devfs_set_cdevpriv fail (148). evdev_revoke

**Citation:** `sys/dev/misc/evdev/evdev.c:118-157`

**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.
