# DF-2126 - Verification Verdict

**Status:** reproduced (source-confirmed)
**Impact:** leak:8bytes
**Confidence:** certain

## Verdict

Source-confirmed: drm_mmap DMA branch (:71,74) stores dma->pagelist[page] (kernel vaddr) into ap->a_result instead of physical address; kernel addr leak; DRM-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/drm_vm.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`.
