# DF-1852 VERDICT

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

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

**Mechanism:** hptproc.c L297 kmalloc(...,M_DEVBUF,M_NOWAIT) no M_ZERO so ke_area stale heap. L303-304 if(nInBufferSize) copyin(lpInBuffer,ke_area,nInBufferSize) return value discarded. L309 Kernel_DeviceIoControl(k

**Citation:** `sys/dev/raid/hptmv/hptproc.c:297-304`

**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.
