# DF-1861 VERDICT

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

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

**Mechanism:** amdgpu_pasid_free_delayed L119 reservation_object_get_fences_rcu returns fences with ref taken per entry (linux_reservation.c:382-386 dma_fence_get_rcu). count>1 path L135-136 passes fences to dma_fen

**Citation:** `sys/dev/drm/amd/amdgpu/amdgpu_ids.c:135-140`

**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.
