# DF-1610 VERDICT

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

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

**Mechanism:** smu7_powertune.c:1120/1122 cac_table = table_info->cac_dtp_table (V1) or dyn_state.cac_dtp_table (legacy) NO NULL check. Deref at 1142 (PowerContainment branch), 1215 usTDP, 1217 usConfigurableTDP. Pa

**Citation:** `sys/dev/drm/amd/powerplay/hwmgr/smu7_powertune.c:1120-1217`

**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.
