# DF-1550 VERDICT

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

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

**Mechanism:** vega10_powertune.c:1294 vega10_initialize_power_tune_defaults fetches tdp_table=table_info->tdp_table then derefs at 1297 (tdp_table->usMaximumPowerDeliveryLimit). Same at 1344 vega10_enable_power_con

**Citation:** `sys/dev/drm/amd/powerplay/hwmgr/vega10_powertune.c:1294-1348`

**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.
