# DF-1628 VERDICT

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

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

**Mechanism:** dce120_resource.c:1065-1072 if(opps[j]==NULL) BREAK_TO_DEBUGGER+dm_error but NO goto controller_create_fail (dce110:1350 correctly does goto). Loop increments j (1075), pipe_count=j (1097) persists NU

**Citation:** `sys/dev/drm/amd/display/dc/dce120/dce120_resource.c:1065-1097`

**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.
