# DF-1592 VERDICT

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

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

**Mechanism:** tws_cam.c:757-758 #ifdef TWS_DEBUG only traces cdb_len>16. 761-764 bcopy(csio->cdb_io.cdb_bytes, cmd_pkt->cmd.pkt_a.cdb[16], csio->cdb_len). csio->cdb_len u8 (0..255) fully user-controlled via pass(4)

**Citation:** `sys/dev/raid/tws/tws_cam.c:757-764`

**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.
