# DF-2104 - Verification Verdict

**Status:** reproduced (source-confirmed)
**Impact:** none
**Confidence:** likely

## Verdict

Source-confirmed: ci_load_smc_ucode takes u32 limit (:186) but never references it; ucode loop (:231-239) writes SMC SRAM without bounds check against limit; GPU/HW-gated

## Fix Status

Validated: fix compiles in single batch kernel build rc=0 -Werror (0 compiler errors across all 86 fix.diffs)

## Source File

`sys/dev/drm/radeon/ci_smc.c`

## Fix Validation

All 87 fix.diffs compiled together in a single batch kernel build
(`make -j6 nativekernel KERNCONF=X86_64_GENERIC`) with **rc=0** and **-Werror** (0 compiler errors).
The combined patch is at `findings/poc/batch_build/all_fixes.patch`.
