# DF-1568 VERDICT

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

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

**Mechanism:** dce112_resource.c:1004-1005 (fallback ENGINE_CLK clks.clocks_in_khz[num_levels-1]), 1032-1034 (fallback MEMORY_CLK), 1040-1041 (primary ENGINE_CLK eng_clks.data[num_levels-1]), 1073-1074 (primary MEMO

**Citation:** `sys/dev/drm/amd/display/dc/dce112/dce112_resource.c:1005-1074`

**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.
