# DF-1926 VERDICT

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

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

**Mechanism:** tws_init_connect L188-208: tws_poll4_response returns unexpected reqid or TWS_INVALID_REQID -> return(FAILURE) but never marks req->state=TWS_REQ_STATE_FREE. tws_get_request(TWS_INTERNAL_CMD_REQ) retu

**Citation:** `sys/dev/raid/tws/tws_hdm.c:188-207`

**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.
