# DF-1842 VERDICT

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

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

**Mechanism:** amr_cam_attach L170 for(chn=0;chn<sc->amr_maxchan;chn++) writes sc->amr_cam_sim[chn] L173 but array declared struct cam_sim* amr_cam_sim[AMR_MAX_CHANNELS=8] (amrreg.h:85/amrvar.h:237). amr_maxchan tak

**Citation:** `sys/dev/raid/amr/amr_cam.c:170-214`

**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.
