# DF-0072 — REPRODUCED (source-only, root-only checkpoint restore)

## 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/kern_checkpoint.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
elf_getfiles: filecount=filehdr.cfh_nfiles (int ckpt.h:47) used as kmalloc(filecount*sizeof(ckpt_fileinfo),M_WAITOK) at :599 with no sign/magnitude check. Negative → SIZE_MAX kmalloc M_WAITOK → panic/hang.
