# DF-1591 VERDICT

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

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

**Mechanism:** tws_cam.c:52 static char tws_sev_str[5][8] (indices 0..4). 435 event.severity = sense->status_block.res__severity & 0x7 (range 0..7). 437 strcpy(event.severity_str, tws_sev_str[event.severity]) severi

**Citation:** `sys/dev/raid/tws/tws_cam.c:52-437`

**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.
