# DF-1711 — Verdict

**Severity:** Low
**Status:** REPRODUCED (source-only confirmation — driver/HW-gated, not runtime-triggered on QEMU guest)
**Impact:** leak:32
**Confidence:** certain

## Verdict
REPRODUCED. The cited bug is confirmed real in the audited source at `sys/dev/powermng/intpm/intpm.c:862`.

## Mechanism
intsmb_bread reads block data into throwaway 'data' variable instead of buf[i], so the user buffer is never filled; copyout ships uninitialized kernel stack to userspace.

## Fix
Change 'data = bus_read_1(...)' to 'buf[i] = bus_read_1(...)' and remove unused 'data' declaration.

The full git-apply-able diff is in `fix.diff`.

## Build validation
fix.diff applies cleanly and compiles with `-Werror` as part of the batch module build
(all 51 fixes applied to /usr/src, kernel+modules built).

## Notes
Source-only confirmation: this finding is in a device driver code path that requires
specific hardware not present in the QEMU guest. The bug is confirmed by source tracing
(cited path:line verified against sys/), and the fix compiles clean. No runtime trigger
was attempted as the relevant device/module is HW-gated.
