# DF-1922 VERDICT

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

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

**Mechanism:** aac_print_fib L240-246 for(i=0;i<sg->SgCount;i++) SgEntry[i] where SgCount read from FIB data (controller-authored) never bounded against AAC_FIB_DATASIZE. Malformed FIB with inflated SgCount reads pa

**Citation:** `sys/dev/raid/aac/aac_debug.c:240-247`

**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.
