# DF-0101 — REPRODUCED (source-only)

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

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

## Expected
leak:8 on the unfixed kernel; after applying `fix.diff` the cited defect is closed.
This finding was verified by source-tracing `sys/kern/kern_ktrace.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
ktrwrite VOP_WRITE entire struct ktr_header sizeof incl caddr_t ktr_buf (ktrace.h:79) which every caller sets to KERNEL addr (&ktp_cache :97 &ktp :155 path :171 etc) but ktrgetheader never touches. Trace file readable by ktrace fd owner leaks kernel heap addresses.
