Subject: iwlwifi: mvm: check sta_id/drain values in debugfs
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit 60765a47a433d54e4744c285ad127f182dcd80aa upstream.
The station ID must be valid, if it's out of range then
the array access may crash. Validate the station ID to
the array length, and also validate the drain value even
if that doesn't matter all that much.
Fixes: 8ca151b568b6 ("iwlwifi: add the MVM driver")
