# DF-2103 - Verification Verdict

**Status:** reproduced (source-confirmed)
**Impact:** corruption
**Confidence:** certain

## Verdict

Source-confirmed: vinum daemonq singly-linked list (daemonq/dqend) manipulated under crit_enter/crit_exit only (dequeue :89-94, append :237-245); crit does not serialize cross-CPU; race yields list corruption/UAF; vinum-module-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/raid/vinum/vinumdaemon.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`.
