# DF-1588 VERDICT

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

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

**Mechanism:** vega10_processpptables.c:1308 entry_index <= state_arrays->ucNumEntries should be <. entry_index==ucNumEntries -> states[ucNumEntries] one ATOM_Vega10_State (12B) past last valid entry. Latent: sole c

**Citation:** `sys/dev/drm/amd/powerplay/hwmgr/vega10_processpptables.c:1308-1312`

**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.
