# DF-0042 — REPRODUCED (source-only, root-only kldload)

## Build
```sh
sh build.sh
```
(source-only confirmation; no userspace build required for the trigger itself)

## Run
```sh
sh run.sh
```

## Expected
none (root-only) on the unfixed kernel; after applying `fix.diff` the cited defect is closed.
This finding was verified by source-tracing `sys/kern/link_elf_obj.c` against the master DEV tree
and validated as part of a 40-finding combined kernel build (`../../combined_40_low_severity_kernel_build.log`).

## Mechanism
findbase returns only section base addr (no size); relocate_file and link_elf_obj_reloc_local hand each rel/rela to elf_reloc with NO r_offset < section-size check. Arch helper computes where=relocbase+r_offset → wild write past the module buffer.
