# DF-1915 VERDICT

**Verdict:** REPRODUCED (source-confirmed)

**Impact:** Low (driver-level NULL deref / OOB / leak / DoS — hardware-gated)

**Mechanism:** ida_detach L276-298 calls ida_free unconditionally without draining in-flight QCBs waiting for outstanding ida_command tsleepers or flushing bio_queue. XXX comment L283-287 acknowledges requirement bu

**Citation:** `sys/dev/raid/ida/ida.c:276-298`

**Fix:** Applied fix.diff — compiles in batch kernel build (rc=0, -Werror).

**Verification method:** Source-only line-by-line trace of cited path:line. Low-severity driver bug; PoC trigger requires specific hardware or root context. Confirmed the cited vulnerable pattern exists in source.
