# DF-1925 VERDICT

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

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

**Mechanism:** tws_ctlr_reset L471-475 stage-1 do{reg=tws_read_reg(TWS_I2O0_SCRPD3)}while(reg&TWS_BIT13) no timeout. Next stage L477-481 correctly bounded TWS_RESET_TIMEOUT plainly oversight. Runtime reachable: tws_

**Citation:** `sys/dev/raid/tws/tws_hdm.c:473-475`

**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.
