# DF-1629 VERDICT

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

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

**Mechanism:** intel_opregion.c:987 pmap_mapbios(asls,OPREGION_SIZE) header mapping. 1031 pmap_mapbios(rvda,rvds) RVDA mapping. Neither registered in DRM iomap_list (only __ioremap_common populates). intel_opregion_

**Citation:** `sys/dev/drm/i915/intel_opregion.c:987-834`

**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.
