# DF-1549 VERDICT

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

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

**Mechanism:** dce110_resource.c:1145-1146 (ENGINE_CLK), 1168-1169 (DISPLAY_CLK), 1186-1187 (MEMORY_CLK) indexes clks.clocks_in_khz[clks.num_levels-1] without num_levels>0 check. clks is stack dm_pp_clock_levels wit

**Citation:** `sys/dev/drm/amd/display/dc/dce110/dce110_resource.c:1146-1187`

**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.
