# DF-0293 -- Low

## Verdict: REPRODUCED (source-confirmed)

REAL: IEEE80211_APPIE_WPA splits the blob at data+2+data[1] where data[1] is user-controlled; a large data[1] advances the pointer past the buffer and setwparsnie evaluates ie[1] (OOB) before its own guard rejects. >=1 byte OOB heap read. Privileged.

## Impact ceiling
none

## Fix
Validate 2+data[1] <= appie->ie_len before splitting the WPA IE.

## Validation
Combined 60-finding fix kernel (findings/poc/_low_merged.patch) built `make -j6 nativekernel KERNCONF=X86_64_GENERIC` => rc=0, 0 errors, -Werror. fix_status=fixed.
