cfg80211: Define nla_policy for NL80211_ATTR_LOCAL_MESH_POWER_MODE commit 8feb69c7bd89513be80eb19198d48f154b254021 upstream. Buffer overread may happen as nl80211_set_station() reads 4 bytes from the attribute NL80211_ATTR_LOCAL_MESH_POWER_MODE without validating the size of data received when userspace sends less than 4 bytes of data with NL80211_ATTR_LOCAL_MESH_POWER_MODE. Define nla_policy for NL80211_ATTR_LOCAL_MESH_POWER_MODE to avoid the buffer overread.
