Two unsolicited event handlers trusted firmware-provided lengths:
mt7996_mcu_rx_all_sta_info_event() looped over res->sta_num without
checking it against skb->len, reading the flex array out of bounds; and
mt7996_mcu_rx_log_message() could compute a negative or oversized length
from tlv->len and feed it to %.*s and the debugfs log path. Bound both
against the actual skb length.
