# DF-1936 VERDICT

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

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

**Mechanism:** vega10_ih_prescreen_iv L288-301 kfifo_put block #if 0 replaced by unconditional kprintf fires on every VM retry page fault whose PASID resolves through pasid_idr (common case for any GPU workload touc

**Citation:** `sys/dev/drm/amd/amdgpu/vega10_ih.c:288-301`

**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.
